Task: Answer the multiple choice question.
Query: Which drug has a 12.186% 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 or b without using any additional words.
Options:
a CCN(CC)S(=O)(=O)c1ccc(NC(=O)C(C)N(c2ccc(OC)cc2)S(C)(=O)=O)cc1
b O=c1[nH]c(NCc2ccccc2)nc2c1CCC2
Answer: b. O=c1[nH]c(NCc2ccccc2)nc2c1CCC2
