Task: Answer the multiple-choice question.
Query: Which compound exhibits a 5.148\% 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] CCN(CC(=O)Nc1ccc2c(c1)OCCO2)C(=O)/C=C/c1ccc(OC)cc1OC
[b] COc1cc(CO)cc(Br)c1OCc1cccnc1
[c] O=C(Nc1cccc(F)c1)c1cccc(S(=O)(=O)N2CCOCC2)c1
[d] C=CCn1c(SC(C)C(N)=O)nc2sc(CC)cc2c1=O
Answer: a. CCN(CC(=O)Nc1ccc2c(c1)OCCO2)C(=O)/C=C/c1ccc(OC)cc1OC
