Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 12.335\% 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) CC(OC(=O)CCCN=C1NS(=O)(=O)c2ccccc21)C(=O)N(C)c1ccccc1
b) O=C(O)c1cc(-c2cccs2)[nH]n1
c) Cc1cccc(CSc2nncc(=O)[nH]2)c1
d) COc1ccc(CCNC(=O)Cn2nnc(C(=O)Nc3cccc(C)c3C)c2N)cc1OC
Answer: b. O=C(O)c1cc(-c2cccs2)[nH]n1
