Problem statement: Answer the MCQ question.
Query: Which compound exhibits a 10.420\% 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) CCO[C@@H]1OC(C(=O)N2CCN(Cc3ccccc3)CC2)=C[C@H](c2coc3ccccc3c2=O)[C@H]1CCCO
b) COc1ccc(-c2nc3c(c(=O)c4ccccc4n3C)c(=O)n2Cc2ccccc2)cc1
c) Cc1ccc(SCC(=O)OCC(=O)NCCc2ccccc2)cc1C
d) COc1ccc(CCNC(=O)CSc2nc(C)nc3sccc23)cc1OC
Answer: a. CCO[C@@H]1OC(C(=O)N2CCN(Cc3ccccc3)CC2)=C[C@H](c2coc3ccccc3c2=O)[C@H]1CCCO
