Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 19.987\% 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. COc1ccc(OCCCC(=O)NCC(C)C)cc1
b. CCCCS(=O)(=O)Nc1ccc(C)cn1
c. Cn1c(=O)c2c(SCC(=O)N3CCOCC3)nc(C3CC3)nc2n(C)c1=O
d. O=C(Nc1ccc(F)cc1)NC1CCCCCCC1
Answer: d. O=C(Nc1ccc(F)cc1)NC1CCCCCCC1
