B what she does in her free time is not my concern

A is the correct answer but why can't I use the rest? They all seem equally correct to me, although D sounds a bit forced.

Care to explain why?

It is a bad question, because the original "What she does in her free time doesn't concern me" can be interpreted as:

"What she does in her free time does not cause me anxiety."
"What she does in ger free time does not involve me."
"What she does in her free time is of no interest or importance to me."

What she does in her free time doesn't concern me.
A. what she does in her free time is none of my businessB. what she does in her free time is not my concern
C. I don't care what she does in her free time

The question was to choose the one with the closest meaning to the original, if that's of any help.

As the sentence stands, A and B are, to my mind, equally appropriate.
A = it's none of my business.
B = it's not the thing I'm dealing with or worried about.

Let's consider this as a typical context: her boss says, "What she does in her free time doesn't concern me, I'm only interested in her behaviour while she's at work".

Here's how the three options could be interpreted.

A. what she does in her free time is none of my business.
– I should take no notice of what she does in her free time.
B. what she does in her free time is not my concern.
– Whatever she does in her free time, that's not what I'm worried about.
C. I don't care what she does in her free time.
– I'm indifferent to what she does in her free time.

Then A, B and C are all possible. Tone and emphasis might suggest that one is closer in meaning than another, but the sentence, as written, can't indicate this.
