Task: Answer the multiple-choice question.
Question: Which compound has a 4.596% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C(Nc1cc(C(F)(F)F)ccc1-n1cncn1)c1ccc(-c2ccccc2)cc1
b CCCCNC(=O)CCn1c(=O)c2ccccc2n(Cc2ccccc2C)c1=O
c COCCNc1cc(NCCOC)c([N+](=O)[O-])cc1[N+](=O)[O-]
d CNC(=S)NNC(=O)c1noc(C)c1C(=O)N1CCN(C(c2ccccc2)c2ccccc2)CC1
Answer: c. COCCNc1cc(NCCOC)c([N+](=O)[O-])cc1[N+](=O)[O-]
