C
All of an organism’s offspring will be the same
D
Organisms can produce more offspring than can survive to maturity.
Explanation: 

Detailed explanation-1: -Overproduction of Offspring Darwin reasoned that populations of all species have the capacity to grow. Simply put, species produce more offspring than can survive.

Detailed explanation-2: -Hint: When the living organisms produce more offspring than that can survive it is known as overproduction of offspring. When an animal overproduces, the survival rate of the most adapted and fittest organism increases and others which are weak will struggle for survival and may die.

Detailed explanation-3: -More offspring are produced than can survive. Organisms are capable of producing more offspring than their environments can support. Thus, there is competition for limited resources in each generation.

Detailed explanation-4: -In the theory of natural selection, organisms produce more offspring than are able to survive in their environment. Those that are better physically equipped to survive, grow to maturity, and reproduce.
