Problem statement: Answer the multiple choice question.
Question: Which drug has a 3.078\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=S1(=O)N(CCN2CC=C(c3c[nH]c4cc(F)ccc34)CC2)c2cccc3c2N1CCC3
b COCCCNC(=S)N/N=C/c1ccc(N(C)C)cc1Cl
c CC1(c2cc([N+](=O)[O-])cc([N+](=O)[O-])c2)CC(C)(C)N(C(=O)c2ccccc2)c2ccccc21
d CC(C)NC[C@H](O)COc1ccc(CC(N)=O)cc1
Answer: a. O=S1(=O)N(CCN2CC=C(c3c[nH]c4cc(F)ccc34)CC2)c2cccc3c2N1CCC3
