Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -2.606\% 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=C1CCCN1C(=O)c1cncc(Br)c1
b.) COc1ccc(Cc2nnc(-c3ccccc3)o2)cc1
c.) COc1ccc(/C=C2\SC(=O)N(CCC(=O)N(C)C3CCS(=O)(=O)C3)C2=O)cc1
Answer: b. COc1ccc(Cc2nnc(-c3ccccc3)o2)cc1
