Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 4.026\% 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, or c without using any additional words.
Options:
a O=C(COc1ccc2ccccc2c1Br)N1CCCC1
b COc1ccc(/C=C2\N=C(SC)N(C)C2=O)cc1
c O=[N+]([O-])c1ccc(CSc2nnc(-c3cccnc3)o2)cc1
Answer: b. COc1ccc(/C=C2\N=C(SC)N(C)C2=O)cc1
