Task: Answer the MCQ question.
Query: Which compound exhibits a -3.427\% 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 other words.
Options:
[a] CC1(C)CC(=O)C(C=Nc2ccc(O)c(N=CC3=C(O)CC(C)(C)CC3=O)c2)=C(O)C1
[b] Cc1nnc(SCC(=O)NC(C)c2ccccc2)[nH]c1=O
[c] O=C(NCCc1c[nH]c2ccccc12)c1ccc(Cl)cc1
[d] O=C(N/N=C/c1ccc([N+](=O)[O-])s1)C(O)c1ccccc1
[e] O=C(c1cccc(Br)c1)N1CCN(c2ccc(N3CCOCC3)nn2)CC1
Answer: c. O=C(NCCc1c[nH]c2ccccc12)c1ccc(Cl)cc1
