Task: Answer the multiple-choice question.
Query: Which drug has a 8.873\% 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=C(CCCN=C1NS(=O)(=O)c2ccccc21)Nc1ccc(Cl)cc1
b: CCOc1ccccc1NC(=O)Cn1c(=O)c2ccccc2n(CC)c1=O
c: COc1cc(NS(=O)(=O)c2ccc(NC(C)=O)cc2)ncn1
d: COc1cccc2c1-c1c(O)cccc1C2=O
Answer: a. O=C(CCCN=C1NS(=O)(=O)c2ccccc21)Nc1ccc(Cl)cc1
