Task: Answer the multiple choice question.
Query: Which drug exhibits a 1.381% 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, b, or c without using any other words.
Options:
(a) Cc1cccc(Oc2sc(C(=O)c3ccccc3)c(N)c2C#N)c1
(b) O=C(OCC(=O)c1c[nH]c2ccccc12)c1cc2ccccc2cc1O
(c) COc1ccc(C2c3c(oc4ccccc4c3=O)C(=O)N2Cc2ccncc2)cc1OC
Answer: b. O=C(OCC(=O)c1c[nH]c2ccccc12)c1cc2ccccc2cc1O
