Task: Answer the MCQ question.
Question: Which drug exhibits a 0.864\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a O=C(O)c1cc(N/N=C/c2ccc(-c3ccccc3)cc2)ccc1Cl
b O=C(CCc1nnc(CCCc2ccccc2)o1)NCC(F)(F)F
c COc1ccc(N2CCN(C(=O)COc3ccccc3)CC2)cc1
d Nn1c(Cc2ccccc2)nc2cc(Cl)ccc2c1=O
e O=C(CCl)NCCCN(C(=O)C(Cl)Cl)c1ccc([N+](=O)[O-])cc1
Answer: c. COc1ccc(N2CCN(C(=O)COc3ccccc3)CC2)cc1
