Which choice best describes the following sentence?

everyone should join a service club, it is a great way to improve the world.

it is a complete and correct sentence.
it features a comma splice.
it is a fused sentence.
it is a rambling sentence.

The correct answer i believe is:

B.) It features a comma splice.

It's about 4 years late, but

B) "It features a comma splice"

Explanation:

A comma splice is when two complete sentences are combined with only a comma between them.  

If we were to separate these 2 sentences it would become:

Everyone should join a service club.

It is a great way to improve the world.

Both of these are complete sentences, meaning, we are given the OK to put a comma (,) in between them to convert it to a comma splice.

Thank you, have a good day!
