How does the use of an informal writing style best help
readers understand the topic?

It helps readers find the exact location of a black hole.

It helps readers visualize the inside of a black hole in
space.

It helps readers learn new black hole names and
phrases.

It helps readers understand how far away black holes
are located

It helps the writers visualize the inside of a black hole.

The other options can described bluntly and scientifically with just names and numbers.

If the writer were to use more formal writing to describe things so abstract like a black hole, it would be hard for the common reader to understand.

for example,

The black hole looks like a giant vacuum of nothingness (informal)

The black hole is like a mass whose Schwarzchild radius is outside of itself (formal)

Which is easier to understand? Most likely the first one because of the use of informal language and writing.

Hope I helped!

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
