Task: Answer the multiple-choice question.
Question: Which drug has a -4.298\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCOC(=O)C1CCCCN1Cc1cccc(C(F)(F)F)c1
b: Cn1c(=O)c(S(=O)C2CCCCC2)c(O)c2ccccc21
c: O=C(Cc1ccccc1)NCC(=O)OC(c1ccccc1)c1ccccc1
d: CNC(=O)c1cc2cc(OC)ccc2oc1=O
Answer: d. CNC(=O)c1cc2cc(OC)ccc2oc1=O
