Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 11.997\% 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 or b without using any other words.
Options:
(a) O=C(O)CCn1c(SCCc2ccccc2)nc2ccccc21
(b) Cc1ccc(C(=O)/C=C/Nc2ccc(S(=O)(=O)Nc3cc(C)nc(C)n3)cc2)cc1
Answer: a. O=C(O)CCn1c(SCCc2ccccc2)nc2ccccc21
