Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 0.565\% 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=C(NCc1ccco1)C1CC(c2ccccc2C(F)(F)F)=NO1
[b] Cc1ccc2c(c1)N(C(=O)CCC(=O)NCc1cccc(F)c1)CCO2
[c] COc1ccc(-c2nc(CN3CCN(Cc4cccc(Cl)c4)CC3)c(C)o2)cc1
[d] O=C(OCC#CCSc1nnc(-c2ccc([N+](=O)[O-])cc2)o1)c1cccs1
Answer: d. O=C(OCC#CCSc1nnc(-c2ccc([N+](=O)[O-])cc2)o1)c1cccs1
