Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 11.696% 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 other words.
Options:
(a) O=C(c1cccc2ccccc12)n1nnc2ccccc21
(b) COc1cccc(-n2nnnc2SCC(=O)Nc2nc3c(s2)CCCC3)c1
Answer: a. O=C(c1cccc2ccccc12)n1nnc2ccccc21
