Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 5.800\% 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 other words.
Options:
(a) CCN1CN=C(NS(=O)(=O)c2ccc(C)cc2)NC1
(b) Cc1ccc(C2CN(CCC(N)=O)C(=O)CO2)cc1
(c) CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)C2C1CC=CCC1
(d) CSCCC(NC(=O)c1cccc(C)c1)C(=O)OCC(=O)Nc1c(C)nn(-c2ccccc2)c1C
Answer: a. CCN1CN=C(NS(=O)(=O)c2ccc(C)cc2)NC1
