Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 20.610\% 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:
a O=C(NC1CCCC1)C1CCN(c2cnccn2)CC1
b S=C1NC[C@H](c2ccccc2)N1CC1CCCCC1
c Cc1c(N(C)S(=O)(=O)c2cccc(C(=O)NCC3CCCO3)c2)c(=O)n(-c2ccccc2)n1C
d Cc1ccc(CNC(=O)C2CCCCN2S(=O)(=O)c2ccccc2)cc1
Answer: a. O=C(NC1CCCC1)C1CCN(c2cnccn2)CC1
