Task: Answer the MCQ question.
Question: Which drug exhibits a 17.887\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COC(=O)c1cccc(NC(=O)c2cccc([N+](=O)[O-])c2)c1
b: CCCNC(=O)N1[C@H]2CC[C@@H]1C(C(=O)OC)=C(c1cccc(OC)c1OC)C2
c: CC1CCC(N2CCN(C(=O)c3ccccc3F)CC2)CC1.O=C(O)C(=O)O
d: Cc1ccc(OCC(=O)N2CCN(S(=O)(=O)c3ccccc3[N+](=O)[O-])CC2)cc1
Answer: b. CCCNC(=O)N1[C@H]2CC[C@@H]1C(C(=O)OC)=C(c1cccc(OC)c1OC)C2
