Task: Answer the multiple choice question.
Query: Which drug exhibits a 11.457\% 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 COc1ccc2c(c1OC)C(=O)OC2Nc1ccccn1
b COc1cc(NS(=O)(=O)c2ccc(NC(=O)COc3cccc(C)c3)cc2)nc(OC)n1
c O=C(Cn1cnc2c(nnn2Cc2ccc(F)cc2)c1=O)NCc1ccccc1
d Cc1c(CCOC(=O)c2cc([N+](=O)[O-])cc([N+](=O)[O-])c2)sc[n+]1CCCCS(=O)(=O)[O-]
Answer: a. COc1ccc2c(c1OC)C(=O)OC2Nc1ccccn1
