Which Is the Best Standard-Form Representation of the Following Argument

Which is the best standard-form representation of the following Argument from Principle?
Killing is only wrong when the thing killed wants not to be killed. (Bacteria, for example, have no desire to live, which is why it's perfectly fine to kill them.) First- trimester fetuses have no desires at all, so they do not have the desire not to be killed. That is why first-trimester abortion is not morally wrong.

A) 1) Killing is only wrong when the thing killed wants not to be killed.
2) First-trimester abortion kills a fetus, which does not want not to be killed. So, First-trimester abortion is not morally wrong.
So,
B) 1) First-trimester abortion is not morally wrong.
2) A fetus has no desires at all.
So, a first trimester abortion is not wrong, because a fetus does not have a desire not to be killed.
C) 1) Bacteria do not have a desire to live.
2) Fetuses do not have a desire to live.
So, first-trimester abortion is not morally wrong.
D) 1) A first-trimester abortion is not morally wrong.
2) Killing is only wrong when the thing killed wants not to be killed. So, first-trimester fetuses do not have the desire not to be killed.
