Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 13.092\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C(c1ccc([N+](=O)[O-])cc1)N(c1ccccn1)c1ccccn1
[b] CCCc1cc(=O)[nH]c(SCC(=O)c2cc(C)n(-c3c(C)n(C)n(-c4ccccc4)c3=O)c2C)n1
[c] COC(=O)c1cccc(N(C(=O)CNC(=O)c2cccs2)C(C(=O)NCC2CCCO2)c2ccc(OC)c(OC)c2)c1
[d] Cc1ccc(C(=O)c2ccccc2C(=O)OCC(=O)NCCc2ccc(Cl)cc2Cl)cc1
Answer: a. O=C(c1ccc([N+](=O)[O-])cc1)N(c1ccccn1)c1ccccn1
