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

Which is the best standard-form representation of the following Argument from Analogy?
First trimester abortions are morally permissible. That early in a pregnancy, the fetus lacks the brain capacity required for even the most minimal conscious experiences, including pleasure and pain. An abortion that removes a cluster of fetal tissues that can't possibly have conscious experiences is not morally different than a surgery that removes a benign tumor.

A) 1) Surgery to remove a benign tumor is morally permissible.
2) 1st-trimester abortion is relevantly similar to surgery to remove a benign tumor.
So, 1st-trimester abortion is morally permissible.
B) 1) 1st-trimester abortion is morally permissible.
2) 1st-trimester abortion is relevantly similar to surgery to remove a benign
Tumor.
So, 1st-trimester abortion is morally permissible.
C) 1) Surgery to remove a benign tumor is morally permissible.
2) People have a right to do what they want with their own bodies. So, 1st-trimester abortion is morally permissible.
D) 1) It is morally permissible to choose whatever surgery you want on your own body.
2) Abortion is a surgery people choose to have on their own bodies. So, abortion is morally permissible.
