Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 1.908\% 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 additional words.
Options:
a: COc1ccc2nc(N3CCC(C)CC3)c(C#N)cc2c1
b: CCOc1ccc(S(=O)(=O)Nc2ccc(C(=O)N3CC(C)OC(C)C3)cc2)cc1
c: S=C(Nc1ccc(Cl)cc1)NC1CCCCC1
d: O=C(CSc1nnc(Cc2cc(=O)[nH]c(=O)[nH]2)n1-c1ccccc1)NCC1CCCO1
Answer: d. O=C(CSc1nnc(Cc2cc(=O)[nH]c(=O)[nH]2)n1-c1ccccc1)NCC1CCCO1
