Task: Answer the multiple choice question.
Query: Which drug exhibits a -84.563% 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, c, d, or e without using any other words.
Options:
(a) COc1ccccc1CCNC(=O)Cn1c(=O)oc2ccccc21
(b) O=C1CC2(CCN(S(=O)(=O)c3ccccc3)CC2)Oc2ccccc21
(c) COc1ccc(C(=O)NCc2nnc(SCC(=O)Nc3ccccc3F)o2)cc1
(d) Cc1ccccc1N1CCN(C(=O)[C@@H]2CCCN2C2=NS(=O)(=O)c3ccccc32)CC1
(e) COc1cc(-c2nc3ccccn3c2/N=C/c2cc(OC)c(OC)c(OC)c2)ccc1O
Answer: b. O=C1CC2(CCN(S(=O)(=O)c3ccccc3)CC2)Oc2ccccc21
