Problem statement: Answer the MCQ question.
Query: Which drug has a 1.696\% 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.) Cc1ccc(NC(=O)COC(=O)c2cccc(OC(F)F)c2)cc1S(=O)(=O)N1CCCCC1
b.) CSc1cnc2c(=O)[nH]c(=O)n(C)c2n1
c.) CCO[C@@H]1OC(C(=O)NCc2nc3ccccc3[nH]2)=C[C@H](C)[C@H]1CCCO
d.) CCOc1ccc(S(=O)(=O)NCCC(=O)NC2CCN(Cc3ccccc3)CC2)cc1
Answer: c. CCO[C@@H]1OC(C(=O)NCc2nc3ccccc3[nH]2)=C[C@H](C)[C@H]1CCCO
