Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -3.429% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=C(Cc1ccccc1)Nc1nccs1
(b) COc1ccc(NC(=O)COc2ccccc2Cc2ccccc2)cn1
(c) COc1ccc(N/C(C)=C/c2scc(-c3ccccc3)[n+]2-c2ccccc2)cc1.[Br-]
(d) O=C(NC1=NCCS1)[C@H](Cc1ccccc1)N1C(=O)c2ccccc2C1=O
Answer: a. O=C(Cc1ccccc1)Nc1nccs1
