Task: Answer the MCQ question.
Question: Which drug exhibits a -1.304% hERG inhibition at a concentration of 10uM?
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)NC2CC2)=C[C@H](c2c[nH]c3ccccc23)[C@H]1CCCO
b. CN(C)C(CNC(=O)c1cccc(S(=O)(=O)Nc2ccccc2Cl)c1)c1ccco1
c. CC(C)c1nc(SCC(=O)c2ccccc2)c2c(=O)n(C)c(=O)n(C)c2n1
d. O=C1c2ccccc2C(Nc2ccccc2F)N1c1cccnc1
Answer: a. CCO[C@@H]1OC(C(=O)NC2CC2)=C[C@H](c2c[nH]c3ccccc23)[C@H]1CCCO
