Task: Answer the multiple choice question.
Question: Which drug has a 12.178% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a Cc1nc(SCc2ccccc2)c2oc3ccccc3c2n1
b CCOC(=O)/C(C#N)=C/C=C1/C=CC=CN1C
Answer: a. Cc1nc(SCc2ccccc2)c2oc3ccccc3c2n1
