If two modern organisms are distantly related in an evolutionary sense, then one should espect that
a. they live in very different habitats.
b. they eat very different types of food
c. their chromosomes should be very similar
d. they should share fewer homlogous structures than two more closely related organisms.
e. they should be members of the same species

d. they should share fewer homologous structures than two more closely related organisms.

Explanation:

One of the bases for determining how related two species of organisms are is by determining the similarities and differences in their anatomy. The number of homologous structures shared between two organisms is what is being considered here. Homologous structures are organs found among different organisms that share similar ancestral origin. These homologous structures shared among the different organism of the same ancestry have similar bone configuration. An example of homologous structure is the forelimb structure which is similar in configuration in humans, bats, and birds.

Homologous structures serve as evidence that points to the fact that two organisms are related or share a common ancestry.  

Consequently, it is inferred that, the more homologous structures that two organisms share, the more closely they are related. Therefore, if two modern organisms are distantly related in an evolutionary sense, then one should expect that they should share fewer homologous structures than two more closely related organisms.
