Task: Answer the multiple choice question.
Query: Which compound exhibits a 12.908\% 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 other words.
Options:
a O=C(O)CCCNC1=NCCC1
b CCOC(=O)c1cnc(-c2ccccc2)nc1Oc1cccc(Cl)c1
c COCCn1c(N)c(N(Cc2ccccc2)C(=O)COc2ccccc2F)c(=O)[nH]c1=O
d COP(=O)(OC)C(Nc1ccc([N+](=O)[O-])cc1)c1ccccc1
Answer: a. O=C(O)CCCNC1=NCCC1
