Task: Answer the multiple-choice question.
Query: Which drug exhibits a -12.281% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
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)(NCc1ccccc1)c1ccc(F)cc1Br
b COC(=O)C1=C(C)Nc2nnnn2C1c1ccc(Cl)cc1Cl
c CCOC(=O)CC1C(=O)NC2CCCCC2N1C(=O)Nc1ccc(Cl)cc1
d CCOC(=O)c1sc(=S)n(-c2ccccc2)c1N
Answer: a. O=S(=O)(NCc1ccccc1)c1ccc(F)cc1Br
