Task: Answer the multiple-choice question.
Query: Which drug exhibits a -5.972\% 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:

[b] CCc1ccc(N=c2c([N+](=O)[O-])nn(-c3ccccc3)n2O)cc1
[c] Cc1nc2cc(NC(=O)NCc3ccc4c(c3)OCO4)ccc2o1
[d] Cc1nn(-c2ccccc2)c(=O)c2ccccc12
Answer: b. CCc1ccc(N=c2c([N+](=O)[O-])nn(-c3ccccc3)n2O)cc1
