Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -2.362\% 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(CC1Oc2ccccc2NC1=O)NCCc1ccccc1
b CO/N=C(/CS(=O)(=O)Cc1ccccc1Cl)c1ccc(Cl)cc1Cl
Answer: a. O=C(CC1Oc2ccccc2NC1=O)NCCc1ccccc1
