Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -20.107% 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) Cc1cccc(C)c1NC(=O)NN=C1CCCCC1
(b) COc1cc2c(cc1OC)CN(Cc1nc3ccsc3c(=O)[nH]1)CC2
(c) Cc1ccc(S(=O)(=O)N2CCCCC2)cc1NC(=O)CSc1nnc(N)s1
(d) Cc1nc2ccc(Br)cc2c2c1CC(CBr)O2
(e) COCCn1c(-c2ccsc2)nc2c1c(=O)[nH]c(=O)n2CC(C)C
Answer: e. COCCn1c(-c2ccsc2)nc2c1c(=O)[nH]c(=O)n2CC(C)C
