The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that cysticercosis is caused by the accidental ingestion of onchospheres. - Cysticercosis is indeed a disease caused by the larval stage of the tapeworm Taenia solium, which is known as cysticerci or bladder worms. 2. **Mechanism of Infection**: - Onchospheres are the larvae of the tapeworm that can be ingested through contaminated food or water. - Once ingested, these onchospheres develop into cysticerci (bladder worms) in the human host. 3. **Consequences of Cysticercosis**: - The bladder worms can migrate to various tissues in the body, including muscles, eyes, and the brain, leading to severe health issues such as blindness or epileptic seizures. 4. **Evaluating the Reason (R)**: - The reason states that Taenia solium is a monogenetic parasite. - This statement is false. Taenia solium is a digenetic parasite, meaning it requires two different hosts to complete its life cycle: humans (the primary host) and pigs (the secondary host). 5. **Conclusion**: - The assertion is true, while the reason is false. Therefore, the correct answer is that the assertion is true and the reason is false. ### Final Answer: - Assertion (A) is true. - Reason (R) is false. - The correct option is that the assertion is true and the reason is false. ---

Onchosphere infection of taenia solium may occur in human being it Causes

Assertion : Taenia solium is a cestode acquired by eating undercooked pork. Reason : Adult Taenia causes cysticercosis in humans.

Assertion (A). Monkey acts as a reservoir host for the parasite that causes African sleeping sickness Reason (R ). Reservoir host lodges the infective stages of the parasite when primary host is not available

Electric fuse is a protective device used in series with an electric circuit or an electric appliance to save it from damage due to overheating porduced by strong current in the circuit or application. Fuse wire is generally made from an alloy of lead and tin, which has hifh resistance and low melting point. It is connected in series in an electric installation. If a circuit gets accidentally short-circuited, a large current flows, then fuse wire melts away, which causes a break in the circuit. The power through fuse (F') is equal to heat energy lost per unit area per unit time (h) (neglecting heat loses from ends of the wire). P = I^2R = h xx 2pirl [R = (rhol)/(pir^2)] where r and l are the length and radius of fuse wire, respectively. A Battery is described by its emf (E) and internal resistance (r). Efficiency of battery (eta) is defined as the ratio of the output to the input power. eta = (Output power)/(Input power) xx 100% But I= E//(R+r), input power = EI. Output power = EI - I^2r , then. eta = ((EI - I^2r)/(EI)) xx 100 = (1-(Ir)/E) xx 100 =[1 - (E/(R+r)) (r/E)] xx 100 = (R/(R+r)) xx 100 We know that output power of a source is maximum when the external resistance is equal to internal resistance, i.e., R = r . The maximum power rating of a 20.0 Omega fuse wire is 2.0 kW. This fuse wire can be connected safely to a DC source (negligible internal resistance) of
