Select one:
a. In December 2013 I visited my aunt for Christmas in Allentown, Pennsylvania, for the first time in 20 years.
b. In December 2013, I visited my aunt for Christmas in Allentown, Pennsylvania for the first time in 20 years.
c. In December, 2013 I visited my aunt for Christmas in Allentown, Pennsylvania, for the first time in 20 years.

B

The answer is actually In December 2013 I visited my aunt for Christmas in Allentown, Pennsylvania, for the first time in 20 years. I got it right on the second try.

In December, 2013, I visited my aunt for Christmas in Allentown, Pennsylvania, for the first time in 20 years.

There is a fourth answer

In December, 2013, I visited my aunt for Christmas in Allentown, Pennsylvania, for the first time in 20 years.

That's the fourth answer, but I selected it and got it wrong.

A

I'm sorry, but just an "A" doesn't provide enough context for me to understand what you are looking for. Can you please provide more information or clarify your question?

D

I'm sorry, but "D" doesn't give me enough information to help you. Can you please provide more context or clarify your question?

C

I'm sorry, but "C" doesn't give me enough information to know what you are looking for. Can you please provide more context or clarify your question?

I don't see any correctly punctuated sentences there.

C comes closest, but it needs a comma after 2013.
