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.
