Task: Answer the MCQ question.
Question: Which drug exhibits a -2.986\% 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] O=c1c2cccnc2n(-c2ccccc2)n1Cc1c(Cl)cccc1Cl
[b] CC(=O)c1ccccc1NC(=O)c1ccc(N2CCCC2=O)cc1
[c] Cc1oc2nc(SCCCC(=O)NCCCO)nc(N)c2c1C
[d] COCCOC(=O)C1=C(C)OC(N)=C(C#N)C1c1ccc2c(c1)OCO2
Answer: d. COCCOC(=O)C1=C(C)OC(N)=C(C#N)C1c1ccc2c(c1)OCO2
