I do not know the options, but, follow this criteria and you should be able to finish the exercise:
Usually, animals that are in captivity are endangered animals, with few individuals left. When we captivate them, the risks of them dying (either naturally or by poaching, hunting, contamination, etc) is lower, since we are taking direct care of them.
Hope it helped,

Micrometre, also called micron, metric unit of measure for length equal to 0.001 mm, or about 0.000039 inch. Its symbol is μm. The micrometre is commonly employed to measure the thickness or diameter of microscopic objects, such as microorganisms and colloidal particles.
DNA replication follows the base pairing rule (A with T and G with C). This ensures identical replication of the genetic information; hence it's conservation. Each daughter DNA double helix contains one old strand of DNA and one newly-synthesized strand of DNA. This is known as the semi-conservative mechanism.
DNA replication also occurs during mitosis which produces haploid gametes. Each parent contributes half of the genetic information during fertilization of two gametes, thus regenerating the diploid number. Genes from both parents are transmitted to the offspring.
There are no true tropic climates
