Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.664\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a O=C(CCn1c(=S)oc2ccccc21)NC1CCCCC1
b Cc1nnc(SCC(=O)Nc2nccs2)n1C(C)C
Answer: a. O=C(CCn1c(=S)oc2ccccc21)NC1CCCCC1
