Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.463\% 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 other words.
Options:
a) C[C@@H](C(=O)NCc1ccccc1)N1C(=O)C2CC=CCC2C1=O
b) O=C(Nc1ccc(C(=O)O)cc1)/C(=C/c1ccc2c(c1)OCO2)NC(=O)c1cccc(Br)c1
c) COC(=O)Nc1ccc2ncn(C)c(=O)c2c1
d) NC1=NC(=O)C(Cc2cccc(Cl)c2)S1
Answer: a. C[C@@H](C(=O)NCc1ccccc1)N1C(=O)C2CC=CCC2C1=O
