Task: Answer the multiple choice question.
Query: Which drug exhibits a -3.138\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CCCOP(=O)(c1ccc(N(C)C)cc1)C(O)c1cc(OC)ccc1OC
(b) O=c1[nH]c(=S)n(-c2ccc(Cl)cc2)c(O)c1/C=N/N1CCOCC1
Answer: b. O=c1[nH]c(=S)n(-c2ccc(Cl)cc2)c(O)c1/C=N/N1CCOCC1
