Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 2.466\% 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) Cc1ccc2[nH]c(O)c(N=Nc3nc4ccccc4s3)c2c1
b) O=C(CSc1nnc(CNC(=O)C23CC4CC(CC(C4)C2)C3)n1-c1ccc(F)cc1)Nc1ccccc1
c) Cc1ccc(Cn2nc(C)c(NC(=O)C3(C)CC3(Br)Br)c2C)cc1
d) CCC(C)C1NC(=O)C(C(C)=O)=C1O
Answer: d. CCC(C)C1NC(=O)C(C(C)=O)=C1O
