Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 0.839\% 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) COCCCN=C1NN=C(c2cc(C)n(-c3ccccc3)c2C)CS1
b) COc1ccc(C2CC(c3cc(Br)ccc3F)n3nnnc3N2)cc1
c) CCOC(=O)c1c(NC(=O)COc2ncnc3ccccc23)sc(C(C)=O)c1C
d) COc1ccccc1Nc1nc2nonc2[nH]c1=O
Answer: c. CCOC(=O)c1c(NC(=O)COc2ncnc3ccccc23)sc(C(C)=O)c1C
