Task: Answer the MCQ question.
Question: Which drug exhibits a -16.129% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CCOc1ccc(NC(=O)CN2C(=O)C3CC=CCC3C2=O)cc1
b CCc1ccc2nc(NC(=O)CSCc3c(C)noc3C)sc2c1
c O=C(Nc1ccccc1[N+](=O)[O-])C1(c2ccccc2)CCOCC1
d O=C(COC(=O)c1ccc(OC(F)F)cc1)NC(=O)NC1CCCC1
Answer: c. O=C(Nc1ccccc1[N+](=O)[O-])C1(c2ccccc2)CCOCC1
