Task: Answer the multiple-choice question.
Query: Which drug exhibits a -13.257% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: COC(=O)c1nn(-c2cccc(C(F)(F)F)c2)c(=O)cc1Sc1ccccn1
b: COc1cccc2c1OC1(C)CC2/C(=C(\C)O)C(=O)N1
Answer: a. COC(=O)c1nn(-c2cccc(C(F)(F)F)c2)c(=O)cc1Sc1ccccn1
