Task: Answer the multiple-choice question.
Query: Which drug has a 8.575\% 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 additional words.
Options:
a: S=c1[nH]c(-c2ccc(Br)cc2)cn1CCc1ccccc1
b: O=C(CCNC(=O)c1ccc(Br)cc1)NCc1ccccn1
c: O=C(Nc1ccccc1)c1ccc(-c2ccccc2)s1
d: CC(NS(=O)(=O)c1ccc(Br)cc1)C(=O)NCC1CCCO1
Answer: a. S=c1[nH]c(-c2ccc(Br)cc2)cn1CCc1ccccc1
