Whenever we see the word "unlike", we know that we will be using the structure, "Unlike X, Y ______" or "Y, unlike X, ______", where X and Y are parallel.

Right now, we have a bunch of stuff breaking up the X and the Y in our comparison, which is what makes this question tricky. We know that anything set off by commas should not be grammatically necessary to our sentence, let's cut out "whose ... instrument" to make it easier to see what we are comparing:

"Unlike the virginal, the harpsichord’s several sets of strings are placed at right angles to its front edge. "

So our X and Y are "virginal" and "harpsichord's several sets of strings. The virginal is an instrument, so we want to compare it to another instrument (like the harpsichord), not an instrument's strings. We can eliminate A.

We can scan through our answer choices to see that only D successfully compares "virginal" to "harpsichord". (Note that C does not follow the correct idiomatic "Unlike X, Y" structure, introducing "in the case of".)
