Task: Answer the multiple-choice question.
Question: Which drug has a 3.126\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CC1CCCN(S(=O)(=O)c2ccccc2[N+](=O)[O-])C1
b COc1ccc(CCNC(=O)COC(=O)C2COc3ccccc3O2)cc1
c CC/C(C)=C1\SC(N2CCOCC2)=NC1=O
d Cc1nc2c(C)cccc2cc1C(=O)N/N=C/c1ccc(N(C)C)cc1
e O=C(Nc1nc(-c2cc(Cl)sc2Cl)cs1)c1cccs1
Answer: a. CC1CCCN(S(=O)(=O)c2ccccc2[N+](=O)[O-])C1
