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.

Here, i fixed your grammar and changed some words. If you'd like, i can help you write it! Im working on a novel or two.
"Far, far away lay a small farm with all the animals you would expect, horses, cows, dogs, and cats. Little Mary Johnson and her brother were wandering around the old run-down house in which they lived. Mary was following her brother. They went to the old Oak tree, exactly where he had seen the beehive. The tiny hill overlooked the little graveyard in town. Mary was scared of the small patch of land by the old church. They reached the top of the hill where Mary could hear a soft humming noise from inside.
She saw the small beehive at the top of the tree. She knew why her brother brought her here at the top of the small hill. See, her brother's class was learning about honey bees, and for most of the summer break, he had been leading her to where he had found the small buzzing, bright yellow but pitch black striped insects."

Answer:
Explanation:
A catalyst is a substance that increases the rate of a chemical reaction without itself getting consumed in the reaction as it helps in decreasing the activation energy. Thus, rate of reaction also increases.
A positive catalyst helps in increasing the rate of a chemical reaction whereas a negative catalyst decreases the rate of a chemical reaction.
Whereas when we increase the temperature then collisions between the particles increases due to increase in kinetic energy. Hence, rate of reaction increases with increase in temperature.
Thus, we can conclude that out of the given options adding a positive catalyst will increase the rate of a chemical reaction.
