Task: Answer the MCQ question.
Question: Which drug exhibits a 0.543\% 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 additional words.
Options:
a. CCO[C@H]1OC(C(=O)NCc2nc3ccccc3[nH]2)=C[C@@H](c2ccc3c(c2)OCO3)[C@@H]1CCCO
b. N=C1C(c2ccccc2)=C(O)C2CCc3ccccc3N12
c. Cc1nc2c(C)cccn2c(=O)c1NC(=O)c1ccc2c(c1)OCO2
d. COc1ccc(C)cc1NC(=O)C1CCN(S(=O)(=O)c2ccccc2)CC1
e. COc1cccc(-c2nc(CS(=O)(=O)CC(=O)NCCCN3CC(C)CC(C)C3)c(C)o2)c1
Answer: a. CCO[C@H]1OC(C(=O)NCc2nc3ccccc3[nH]2)=C[C@@H](c2ccc3c(c2)OCO3)[C@@H]1CCCO
