Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -1.782\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) O=C1N/C(=N\N=C\c2cccs2)SC1Cc1ccc(Cl)cc1
(b) CCOC(=O)c1c(C2CC2)csc1NC(=O)CSCc1c(C)noc1C
Answer: a. O=C1N/C(=N\N=C\c2cccs2)SC1Cc1ccc(Cl)cc1
