Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 7.637\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(Nc1ccc(S(=O)(=O)Nc2cnc3ccccc3n2)cc1)c1ccc(Br)o1
(b) O=c1[nH]c2ccccc2cc1-c1noc(-c2cccnc2)n1
(c) CCn1nc(C)c(NC(=O)c2ccc(Cl)cc2)c1C
Answer: b. O=c1[nH]c2ccccc2cc1-c1noc(-c2cccnc2)n1
