Problem statement: Answer the multiple-choice question.
Query: Which drug has a 18.195\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CCOC(=O)C1=C(COC(=O)COc2ccc(Br)cc2)NC(=O)NC1C
b. CN(c1ccc(C(=O)N2CCCCC2)cc1)S(=O)(=O)c1cccs1
c. COc1cc(OC)c(S(=O)(=O)Nc2ccc(C)cn2)cc1NC(C)=O
d. COc1cccc(/C=C/c2n[nH]c(=O)c(C#N)c2C)c1
Answer: a. CCOC(=O)C1=C(COC(=O)COc2ccc(Br)cc2)NC(=O)NC1C
