Problem statement: Answer the multiple choice question.
Query: Which drug has a 14.200\% 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(NCc1cccs1)C(=O)NCC(c1ccco1)N1CCN(c2ccccc2)CC1
b: CC1CCCCC12NC(=O)N(CC(=O)c1ccc[nH]1)C2=O
Answer: a. O=C(NCc1cccs1)C(=O)NCC(c1ccco1)N1CCN(c2ccccc2)CC1
