Problem statement: Answer the multiple choice question.
Query: Which compound has a 10.261\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=C(CCSc1ccccc1)Nc1ccc(OCc2ccccc2)cc1
b) C=CCn1c(O)c(C=NCCN2CCNCC2)c(=O)[nH]c1=O
Answer: b. C=CCn1c(O)c(C=NCCN2CCNCC2)c(=O)[nH]c1=O
