Problem statement: Answer the multiple choice question.
Question: Which drug has a 12.971\% 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, d, or e without using any additional words.
Options:
a) COc1ccc(CN2CCN(S(=O)(=O)c3ccccc3)CC2)c(OC)c1.O=C(O)C(=O)O
b) COc1ccc(C(=O)c2c3ccc(OC)cc3[n+]([O-])n2Cc2ccc(C(N)=O)cc2)cc1
c) O=C(NC(=S)Nc1cc([N+](=O)[O-])ccc1O)c1cccnc1
d) CCOC(=O)N1CCN(CC(=O)Nc2sccc2C#N)CC1
e) Cc1cc(C)c2cc3c(nc2c1)SC(=NCC(C)C)N(CCN1CCOCC1)C3
Answer: c. O=C(NC(=S)Nc1cc([N+](=O)[O-])ccc1O)c1cccnc1
