Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 2.516\% human ether-à-go-go related gene (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. COC(=O)/C=C1\OC(c2ccccc2)=CC1=O
b. Cc1c(C#N)c2ncn(Cc3ccccn3)c(=O)c2n1-c1ccccc1
c. C=CCN(c1ccccc1C(=O)O)S(=O)(=O)/C=C/c1ccccc1
d. CCOCC(=O)Nc1cccc(Br)c1
Answer: d. CCOCC(=O)Nc1cccc(Br)c1
