Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 13.391\% 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, or d without using any other words.
Options:
a COc1ccccc1C(=O)ON=C1c2ccccc2-c2ccccc21
b Nc1nc(Cl)cc(Nc2ccccc2Cl)n1
c COc1ccc(C(=O)NC(=S)Nc2ccc3[nH]c(=O)[nH]c3c2)cc1
d CC(=O)c1ccc(NC(=O)CN2C(=O)NC(C)(C3CCCCC3)C2=O)cc1
Answer: b. Nc1nc(Cl)cc(Nc2ccccc2Cl)n1
