Task: Answer the multiple choice question.
Query: Which compound exhibits a 21.722\% 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 additional words.
Options:
a) O=C(O)COc1ccc(NC(=O)c2cccs2)cc1
b) Cc1noc(NS(=O)(=O)c2ccc(NC(=O)CSc3nnc4c(n3)[nH]c3ccccc34)cc2)c1C
c) Cc1ccc(NC(=O)Cc2cn3ccsc3n2)nc1
d) Cc1cccc(-c2noc(CN(C(C)C)S(=O)(=O)c3ccc(Cl)cc3)n2)c1
Answer: a. O=C(O)COc1ccc(NC(=O)c2cccs2)cc1
