The answer is,
Here?s the explanation:
The best way to look at this or any type
of multiple-choice question, is to eliminate
the obviously incorrect answers.
We?ll let answer b. sit out, it?s obvious
this sentence has problems.
That leaves, Answers a., c. and d.
Answer a. is Lacks parallel parts. For
this one to be correct, the sentence would
need a series of similar elements.
I enjoy Physics, Calculus and Electronics.
We shall not flag or fail!
Answer d. is Comma Splice. For this one
to be correct, both parts of the sentence
would have to be independent of each other.
He went to the store, he bought nails.
People are running, it must be a riot.
The correct answer, c. is a dangler or
a misplaced modifier. The subject of
the sentence is not being described by
Swimming very rapidly, his mask peeled from his face.
Racing to look out the window, the UFO burst overhead.
And I found a nice webpage with
a good (long) mnemonic to help you
mind your danglers.

?Honesty is still the best policy. If you say "this
was done" instead of "I did this," then you
legitimately prompt the question: "By whom?"
(Sometimes "by whom" is obvious, sometimes it is
not.) Worse, you are thrown into the passive
voice, and good writing demands the active voice.
Still worse, by using the passive voice
participles start dangling all over the place. (Do
you recognize a dangling or unattached participle
when you see one? There is one right there staring
you in the face, back in the last sentence outside
the bracket. If you don't already see how silly
that sentence is, let's turn it around, and you
will: "Still worse, participles start dangling all
over the place by using the passive voice." The
participles aren't using the passive voice, you
are; so don't. Use "I".) Incidentally, a dangler
can be undangled by turning the participle into a
gerund (and if you don't recognize the dangler
right there you've got problems): to turn a
participle into a gerund - or maybe a gerundive:
the distinction beats me - simply put a "the" in
front of it and an "of" after it: "a dangler can
be undangled by the turning of the participle into
a gerund" (or a gerundive, as the case may be; who
