Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -23.018\% 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, c, or d without using any additional words.
Options:
[a] COc1cccc(-n2c(Cc3cc(=O)[nH]c(=O)[nH]3)nnc2SCC(=O)N2CCCCC2)c1
[b] COc1ccc(NS(=O)(=O)c2cccc(C(=O)NCC(c3ccccc3OC)N3CCCC3)c2)cc1
[c] Clc1cc(Br)ccc1OCCOCCN1CCCC1.O=C(O)C(=O)O
[d] COc1ccc(CN2CCN(C(=O)c3cc(C4CC4)nn3-c3ccccc3)CC2)cc1F
Answer: c. Clc1cc(Br)ccc1OCCOCCN1CCCC1.O=C(O)C(=O)O
