Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -8.421\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. O=C(NCC1CCCO1)Nc1ccc(Cl)cc1
b. Cc1ccc(NS(=O)(=O)c2c(C)nc3sccn3c2=O)c(C)c1
c. CCCC(=O)Nc1cccn(Cc2ccccc2Br)c1=O
d. CC(=O)Nc1ccc(SCC(=O)N(C)C2CCS(=O)(=O)C2)cc1
e. CCOc1cc(/C=C2\SC(N3CCCCC3)=NC2=O)ccc1O
Answer: a. O=C(NCC1CCCO1)Nc1ccc(Cl)cc1
