Answer

Brief Explanations:

We need to choose the correct pronoun according to English grammar and context. Here, the subject is the gravitational influence of the exoplanet, a singular non - human entity. "It" is used to refer to a singular non - human thing. "Them" is plural, "these" is a demonstrative pronoun used in a different context for plural things, and "each" is used for individual members of a group in a different usage pattern.
