Task: Answer the multiple-choice question.
Query: Which drug exhibits a 15.248\% 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 CCn1cc(CN2CCC(n3nccc3NC(=O)C3CCCC3)CC2)cn1
b CC1=C(C(N)=O)C(c2ccc(Br)cc2)n2ncnc2N1
c COc1ccc(CC(=O)OCC(=O)NCC2CCCO2)cc1OC
d O=C(O)c1ccc(N2Cc3ccccc3C2)cc1O
Answer: b. CC1=C(C(N)=O)C(c2ccc(Br)cc2)n2ncnc2N1
