d) you know the feeling. it's minutes until the school bus comes, but you just rolled out of bed, threw on some clothes, barely brushed your teeth, and now you’re racing out the door to catch the bus.

The sentences that are correctly punctuated are Sentences B, C, and D.

Sentence A is not correctly punctuated as it is a run-on sentence.  Contrary to what the name “run-on sentence” implies, a run-on sentence is not a sentence that runs on with lots of words.  It, for instance, is entirely possible for a grammatically correct sentence to have, even, over a hundred words as long as it is properly punctuated.  In fact, a run-on sentence is a sentence this simply missing punctuation.  For a sentence to be considered a run-on sentence the appropriate punctuation will be missing between two complete thoughts.  That said, Sentence A has two complete thoughts, and they are as follows:

Some workers train dogs to become service dogs for people who need assistance

others workers accompany the mobile spay and neuter project for inner-city pet owners

There are three ways to correct a run-on sentence.  

1) You could use a period between the two complete thoughts:

Some workers train dogs to become service dogs for people who need assistance.  Other workers accompany the mobile spay and neuter project for inner-city pet owners.

2) You could use a semicolon between the two complete thoughts:

Some workers train dogs to become service dogs for people who need assistance; other workers accompany the mobile spay and neuter project for inner-city pet owners.

3) You could use a comma/conjunction between the two complete thoughts:

Some workers train dogs to become service dogs for people who need assistance, and other workers accompany the mobile spay and neuter project for inner-city pet owners.
