Problem statement: Answer the multiple-choice question.
Query: Which drug has a -15.657\% 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 other words.
Options:
[a] N/C(=N/O)C(c1ccccc1)c1ccccc1
[b] Cc1ccc(Nc2nc(CSc3nnnn3C)cs2)cc1
[c] CCCn1c(-c2cccc([N+](=O)[O-])c2)nc2c1c(=O)[nH]c(=O)n2Cc1ccccc1
[d] Cc1cc(Cl)ccc1OCCCC(=O)N1CCN(C)CC1
[e] O=C(Cc1ccc([N+](=O)[O-])cc1)Nc1cc(C(F)(F)F)cc(C(F)(F)F)c1
Answer: c. CCCn1c(-c2cccc([N+](=O)[O-])c2)nc2c1c(=O)[nH]c(=O)n2Cc1ccccc1
