Read the given sentences, each with one or two blanks and select the option that correctly fills any four of these.
(i) P causes ulcers in stomach and duodenum. (ii) diseases last for only short period of time but are severe. (iii) R diseases are anatomical or physiological abnormalities present since birth, e.g. S (iv) Malaria causing microbes are transmitted through bite of infected T and move to U and then red blood cells of humans.

Options

A. P-Salmonella typhi, R-Chronic, T-Sandfly, U-Brain cells
B. Q-Acute, S-Kala azar, T-Tsetse fly, U-Pancreas
C. P-Helicobacter pylori, R-Congenital, S-Cleft palate, U - Liver
D. Q-Chronic, R-Acute, T-Aedes mosquito, U-Spleen

Explanation

To solve the question, we need to fill in the blanks in the given sentences with the correct terms based on the context provided. Let's break it down step by step.

### Step-by-Step Solution:

1. **Sentence (i):** "P causes ulcers in stomach and duodenum."
- The causative agent for ulcers in the stomach and duodenum is a type of bacteria known as **Helicobacter pylori**. Therefore, we can fill in the blank for P as **Bacteria**.

2. **Sentence (ii):** "Diseases last for only short period of time but are severe."
- Diseases that last for a short period but are severe are referred to as **Acute Diseases**. So, we fill in the blank for this sentence as **Acute**.

3. **Sentence (iii):** "R diseases are anatomical or physiological abnormalities present since birth, e.g. S."
- Diseases that are present since birth are known as **Congenital Diseases**. Thus, we fill in the blank for R as **Congenital Diseases**. For S, an example of a congenital disease is **Cleft Palate**.

4. **Sentence (iv):** "Malaria causing microbes are transmitted through bite of infected T and move to U and then red blood cells of humans."
- The malaria-causing microbe is **Plasmodium**, and it is transmitted through the bite of the **female Anopheles mosquito** (which we will fill in for T). The next step involves the microbe moving to the **Liver** (which we will fill in for U) before it enters the red blood cells.

### Final Answers:
- P: Bacteria
- Q: Acute
- R: Congenital Diseases
- S: Cleft Palate
- T: Female Anopheles mosquito
- U: Liver

### Summary of Filled Blanks:
1. P = Bacteria
2. Q = Acute
3. R = Congenital Diseases
4. S = Cleft Palate
5. T = Female Anopheles mosquito
6. U = Liver
