Verified step by step guidance

Identify the type of elimination reaction: In a basic solution, elimination reactions typically proceed via the E2 mechanism, which requires a strong base to abstract a proton and a good leaving group.

Analyze the structure of each compound: Look for the position of the leaving group (Br) and the hydrogen atoms that can be abstracted by the base. The more accessible the hydrogen, the faster the elimination.

Consider the stereochemistry: For E2 reactions, the leaving group and the hydrogen must be antiperiplanar. Check each compound to see if this geometric requirement is met.

Evaluate the stability of the resulting alkene: The more substituted the alkene, the more stable it is, which can influence the rate of elimination.

Determine the compound with the best conditions for E2 elimination: The compound that has the most accessible antiperiplanar hydrogen and forms the most stable alkene will undergo elimination the fastest.
