Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -1.353\% 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. CCOc1ccc(-n2nc(C(=O)N3CCN(CC)CC3)c3ccccc3c2=O)cc1
b. CCOC(=O)C1(C(F)(F)F)N=C(C(F)(F)F)Nc2cc(C)c(C)cc21
c. Cc1ccc(NC(=S)NCc2ccco2)c(C)c1
d. CC(=O)C1C(c2ccc([N+](=O)[O-])cc2)c2c(noc2C)CC1(C)O
Answer: a. CCOc1ccc(-n2nc(C(=O)N3CCN(CC)CC3)c3ccccc3c2=O)cc1
