Task: Answer the MCQ question.
Query: Which drug exhibits a 2.577\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) O=C(CNC(=O)c1ccc(S(=O)(=O)N2CCCC2)cc1)N/N=C/c1ccc(Cl)cc1Cl
(b) O=C(CC(c1ccccc1)c1ccccc1)NCCOCc1ccccc1
(c) CCOn1c(=O)c(-c2ccc(Br)cc2)[n+]([O-])c2ccccc21
(d) Cc1nnc(N2CCN(c3ccccc3)CC2)[nH]c1=O
(e) O=C(CCc1ccccc1)N/N=C/c1cccc([N+](=O)[O-])c1
Answer: d. Cc1nnc(N2CCN(c3ccccc3)CC2)[nH]c1=O
