Problem statement: Answer the multiple choice question.
Question: Which drug has a 18.338\% 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)c1c(NC(=O)c2ccnn2C)sc(C)c1C
[b] Cc1ccc(S(=O)(=O)N2CCCCC2)c(C)c1NS(C)(=O)=O
[c] COc1ccc(CC2(CO)COc3ccccc3C2=O)cc1
[d] Cc1nn2c(N3CCN(C)CC3)c3c(nc2c1-c1ccccc1)CCCC3
Answer: a. CCOC(=O)c1c(NC(=O)c2ccnn2C)sc(C)c1C
