Question

how would you protect the adults in the most effective, practical and noninvasive way, considering the species and the fact that we are on an exoplanet?
a) provide an extra source of food
b) eliminate species that compete with the goslins
c) reduce the impact of the filtering system on the goslins source of food
d) grow their food artificially

Explanation:

Providing an extra food - source is a non - invasive way to protect adults on an exoplanet. Eliminating competing species is invasive. Reducing the impact of a filtering system may not be directly related to protection and growing food artificially may not be the most practical in an exoplanet context without proper infrastructure.

Answer:

A. Provide an extra source of food
