I would go with B, or Ways to build immunity to diseases. Why? Well, just by using the word biology, we can use process of elimination. The prefix “bio” means life, so C and D already would be out. The suffix “ology” means the study of, so the word biology means the study of life. Because biology often has to do with diseases and finding cures to sustain human life spans, the only logical answer would be B. A would make no sense in terms of biology.

Hey Pal,
I have not received any letter from you off late. How have you been? Two months back when you wrote to me, you said you were going to Tokyo for your winter vacation. How has that experience been? Write to me about your time spent in Tokyo.
With summer coming up in a couple of months, my father has promised to take us to Kashmir. It is really beautiful in summer and I am really eager to visit the place. What are your plans for summer? Are you planning to come to India like you said earlier? If you are planning, what places do you want to visit? Do you have any friends and family in India?
Please visit us too if you have time. Do let me know in advance about your travel plans so we will try to plan ours around it. Do write to me when you get this letter. I am enclosing some photographs of our Christmas vacation in Goa. Hope you like them.
Cheers,
your name
