Calotropis is protected from the predators by producing

Options

A. Opium
B. Cardiac glycosides
C. Strychnine
D. Nicotine

Answer

To solve the question about how Calotropis is protected from predators, we can follow these steps:

### Step 1: Understand the question
The question asks how Calotropis, a genus of flowering plants, protects itself from predators. We need to identify the correct compound that provides this protection.

### Step 2: Identify the characteristics of Calotropis
Calotropis is known for producing latex, which is a milky substance. This latex contains toxic compounds that deter herbivores and other predators.

### Step 3: Analyze the options given
The options provided are:
- A) Opium
- B) Cardiac glycoside
- C) Trignin
- D) Nicotine

We need to evaluate which of these compounds is associated with the protective mechanisms of Calotropis.

### Step 4: Research the compounds
- **Opium** is derived from poppy plants and is not related to Calotropis.
- **Cardiac glycosides** are toxic compounds found in some plants, including Calotropis, and can cause harmful effects on animals that consume them.
- **Trignin** is not a well-known protective compound associated with Calotropis.
- **Nicotine** is primarily found in tobacco plants and is not relevant to Calotropis.

### Step 5: Conclude the answer
Based on the information gathered, Calotropis protects itself from predators by producing **cardiac glycosides**, which are toxic and deter herbivores. Therefore, the correct answer is **B) Cardiac glycoside**.

### Final Answer
Calotropis is protected from predators by producing **cardiac glycosides**.
