Problem statement: Answer the multiple choice question.
Query: Which drug has a 0.272\% 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, d, or e without using any additional words.
Options:
a.) O=C(CC1CCCCC1)Nc1c2c(nn1-c1ccc(F)cc1)CS(=O)(=O)C2
b.) CCNC(=O)c1ccccc1-c1nc(-c2ccccc2Cl)no1
c.) COc1ccc([N+](=O)[O-])cc1NC(=O)CCS(=O)(=O)c1ccc(Br)cc1
d.) CC(=O)C1=C(O)C(=O)N(CCc2c[nH]c3ccccc23)C1c1ccc(C)cc1
e.) CCOc1cc(NC(=S)NCc2ccco2)c(OCC)cc1NC(=O)CC
Answer: a. O=C(CC1CCCCC1)Nc1c2c(nn1-c1ccc(F)cc1)CS(=O)(=O)C2
