The answer would most likely be B, this is because the more animals that are birthed, the more that will live and grow (assuming that they have enough resources for them).
Hope this helps!
Phase II of clinical trial.
Explanation:
Clinical trials aim to determine the efficiency of a proposed or experimental drug on people before it is finalized and sold into the market.
This is necessary so that the effectiveness and any side effects of the drug could be assessed before hand.
The clinical trial design explains four phases :
Phase I involves trial of the experimental drug on healthy people who come for the trial with own consent. They are paid for the trials.
Phase II involves comparing the effects of drug with general treatment. In this stage hundreds of effected people receive the drug and another group of hundreds of effected people receive the placebo.
Phase III involves testing of the drug on thousands of patients.
Phase IV involves taking reviews on the effectiveness of the drug. This stage comes after the drug has been released into the market. Any kind of ban on a drug can be imposed at this stage.

Answer:
Each cell can receive and respond to signals that they get from their surroundings. The three stages involved in transduction are reception, transduction, and response.
Reception: It involves receptor molecules and inducers. Receptors can be intracellular or extracellular. Receptors like G- protein-coupled receptor, receptor tyrosine kinase, and signaling molecules are the items that come under reception.
Transduction: In transduction, signals are transferred from outside of the cell to the inside of the cell. Secondary messengers are majorly involved in signal transduction like cAMP, cGMP, IP3, Ca2+, nitric oxide, etc.
Response: The response of cell signaling includes processes like protein synthesis, cell division, cell growth, etc.
