Task: Answer the multiple choice question.
Question: Which drug exhibits a -29.467% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(/C=C/c1cccc([N+](=O)[O-])c1)NCCSCc1ccco1
b O=C(c1ccccc1S(=O)(=O)NCC(O)COc1ccc([N+](=O)[O-])cc1)N1CCCCC1
c COc1cccc(NC(=O)COc2ccc(Br)c(C)c2)c1
d COc1ccc(Cl)cc1NC(=O)CN(C)C(=O)c1ccc(C)s1
Answer: a. O=C(/C=C/c1cccc([N+](=O)[O-])c1)NCCSCc1ccco1
