Task: Answer the MCQ question.
Query: Which drug has a -8.166% 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: O=c1c2ccccc2c(-c2ccccc2)nn1-c1cc(Cl)ccc1[N+](=O)[O-]
b: Cl.O=C(CN1CCOCC1)c1ccc(Br)cc1
c: Cc1ccc(NC(=O)CN(c2ccc(Cl)cc2)S(=O)(=O)c2cc([N+](=O)[O-])ccc2Cl)c(C)c1
d: O=c1c2cc(N3CCOCC3)ccc2[nH]c(=S)n1CCc1ccccc1
Answer: a. O=c1c2ccccc2c(-c2ccccc2)nn1-c1cc(Cl)ccc1[N+](=O)[O-]
