Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.536% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) O=C(O)Cn1cc(C(=O)c2cccs2)c2ccccc21
b) Cn1c(=O)n(C/C=C/c2ccccc2)c(=O)c2c1nc1n2CCCN1c1ccc(F)cc1
c) Cc1ccc(C(=O)O/N=C(\c2ccccc2)c2ccncc2)cc1
d) COc1ccc(NC(=O)CN(C)C(=O)CNC(=O)c2ccc3c(c2)OCO3)cc1
Answer: b. Cn1c(=O)n(C/C=C/c2ccccc2)c(=O)c2c1nc1n2CCCN1c1ccc(F)cc1
