• B. Kin selection theory given by Hamilton
• C. Mutation theory given by Hugo de Vries
• D. Nepotism

Answer 1

Answer: (B)

Kin selection theory given by Hamilton

• An organism is said to behave altruistically when its behaviour benefits other organisms (kin) at a cost to itself.
• By behaving altruistically, an organism reduces the number of offspring it is likely to produce itself, but increases the number that other organisms (kin) are likely to produce.
  
• This is called kin selection.
