Task: Answer the MCQ question.
Query: Which drug exhibits a 14.161\% 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(CNC(=O)c1ccc(Cl)cc1Cl)NCc1ccccn1
b. COc1ccc(CCNC2=C(Cl)C(=O)N(CCc3ccc(OC)c(OC)c3)C2=O)cc1OC
c. O=C(NCc1nc2ccccc2[nH]1)C1=C[C@@H](c2ccc(C(F)(F)F)cc2)C[C@@H](OCc2ccc(CO)cc2)O1
d. O=C(c1ccc(N2C(=O)CCC2=O)cc1)N1CCN(c2ccccc2)CC1
Answer: d. O=C(c1ccc(N2C(=O)CCC2=O)cc1)N1CCN(c2ccccc2)CC1
