Task: Answer the multiple choice question.
Query: Which drug exhibits a 14.238\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=C(Cc1cccs1)N/N=C\c1ccc(O)cc1
b) Cc1ccccc1CN1C(=O)c2ccccc2Sc2ccc(C(=O)NCCN3CCOCC3)cc21
Answer: a. O=C(Cc1cccs1)N/N=C\c1ccc(O)cc1
