Task: Answer the MCQ question.
Question: Which drug exhibits a 5.498\% 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 additional words.
Options:
a: Cn1cc(C(=O)N2CCN(c3ccccn3)CC2)c(=O)c2cc(S(=O)(=O)N3CCOCC3)ccc21
b: Cc1cccc(NC(=O)N2CCC(n3nnc4cc(C)ccc43)CC2)c1
c: O=C(C1CCC1)N1CCN(S(=O)(=O)c2ccc(Br)cc2Cl)CC1
d: CCOC(=O)C1=C(O)/C(=C/c2ccc(OCC(=O)O)c(OC)c2)SC1=Nc1ccc(OCC)cc1
Answer: d. CCOC(=O)C1=C(O)/C(=C/c2ccc(OCC(=O)O)c(OC)c2)SC1=Nc1ccc(OCC)cc1
