Task: Answer the multiple-choice question.
Question: Which drug exhibits a 9.435\% 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=C1NC(=Nc2ccc3ccccc3c2)S/C1=C/c1ccco1
(b) C=CCn1c(N)cc(=O)nc1SCC(=O)Nc1cccc2ccccc12
Answer: a. O=C1NC(=Nc2ccc3ccccc3c2)S/C1=C/c1ccco1
