Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 6.685\% 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] Cn1nccc1C(=O)Nc1cccnc1
[b] O=C(NC1CCCC1)C(c1ccncc1)N(C(=O)Cc1cccs1)c1cccc(F)c1
Answer: b. O=C(NC1CCCC1)C(c1ccncc1)N(C(=O)Cc1cccs1)c1cccc(F)c1
