Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.024\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. O=S(=O)(c1ccc(-c2ccccn2)s1)N1CCC2(CC1)OCCO2
b. COc1cccc(-c2ncc3ccccn23)c1.O=C(O)C(=O)O
c. O=C(NCC1CCCO1)c1ccccc1S(=O)(=O)c1ccc([N+](=O)[O-])cc1
d. COc1ccc(NC(=O)CN(C)C(=O)C2CCCO2)cc1
Answer: b. COc1cccc(-c2ncc3ccccn23)c1.O=C(O)C(=O)O
