Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 3.655\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COc1cccc(NC(=O)CSc2c3c(nc4ccccc24)CCCC3)c1
[b] CC(O)/C=C/c1ccc2ccccc2n1
[c] CCOc1c(N2CCCCC2)c(=O)c1=O
[d] Cn1c(SCC(=O)N2CCCC2=O)nc2ccccc21
Answer: b. CC(O)/C=C/c1ccc2ccccc2n1
