Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.660\% 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 other words.
Options:
a) Cc1ccc(S(=O)(=O)N2CCCC(C(=O)NC3CCCC3)C2)cc1
b) CCCCN=Cc1c(C)[nH]n(-c2ccccc2)c1=S
c) CC12CCC(=O)C=C1CCC1C2C(=O)CC2(C)C1CCC2(O)C(=O)CO
d) O=C(/C=C/c1ccccc1[N+](=O)[O-])Nc1cccnc1
Answer: c. CC12CCC(=O)C=C1CCC1C2C(=O)CC2(C)C1CCC2(O)C(=O)CO
