Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 5.341\% 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(C)OC(N)=C(C#N)C12C(=O)Nc1ccc(C)cc12
b.) COCCCN(C(=O)c1ccco1)c1nc(-c2cc(OC)ccc2OC)cs1
c.) Cc1ccc(C(=O)Nc2nc(-c3ccc([N+](=O)[O-])cc3)cs2)o1
d.) CCC(CC)C(=O)Nc1ccc(C)c(O)c1
Answer: d. CCC(CC)C(=O)Nc1ccc(C)c(O)c1
