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

Which is the best standard-form representation of the following Argument from Analogy?
Imagine that you are a famous concert pianist. One day, while walking along the train tracks, you see a stranger about to be crushed by a train. You know you could save them but in the process you'd lose your hand. Now, it would certainly be nice of you to sacrifice your hand, and thus your career, to save the life of this stranger. But this much is clear: the law should not require you to sacrifice your hand for the sake of the stranger.
Carrying a pregnancy to term likewise involves significant physical sacrifice. If the law shouldn't require you to sacrifice your hand for a stranger, the law shouldn't require you to carry a pregnancy to term, either.

A) 1) A person shouldn't be legally required to carry a pregnancy to term.
2) Carrying a pregnancy to term is relevantly similar to the pianist crushing their hand to save the stranger.
So, the pianist shouldn't be legally required to crush their hand to save the stranger.
B) 1) the concert pianist should not be legally required to crush their hand to save the stranger.
2) Carrying a pregnancy to term is relevantly similar to the pianist crushing their hand to save the stranger
So, a person should not be legally required to carry a pregnancy to term.
C) 1) The law shouldn't require you to sacrifice yourself to save others.
2) The concert pianist shouldn't have to sacrifice their hand to save the stranger. So, a person shouldn't be legally required to carry a pregnancy to term.
D)
1) A person shouldn't be legally required to carry a pregnancy to term.
2) Carrying a pregnancy to term is relevantly similar to the pianist crushing their hand to save the stranger.
So, a person should not be legally required to carry a pregnancy to term.
