Task: Answer the multiple choice question.
Question: Which drug has a 12.598\% 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, b, or c without using any additional words.
Options:
[a] CCN(CC)CCCn1c(=S)[nH]c2ccccc2c1=O
[b] O=C(Oc1ccc2c(-c3ccccc3)cc(=O)oc2c1)c1cccs1
[c] O=C(Nc1nnc(Cc2ccccc2)s1)c1cnccn1
Answer: c. O=C(Nc1nnc(Cc2ccccc2)s1)c1cnccn1
