Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 6.587\% 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, d, or e without using any additional words.
Options:
(a) COc1ccc(/C(C)=N/NC2=NCCN2)cc1Cl
(b) Cc1cccc(C)c1NC(=O)Cn1cnc2c(=O)n(C)c(=O)n(C)c21
(c) Cc1ccc(C(=O)N2CCN(c3ncnc4c(-c5ccccc5)nsc34)CC2)cc1
(d) COc1cccc(CN(C)C(=O)c2ccccc2Sc2ccccc2C#N)c1OC
