Step 1: The question asks for a word that means the same as Expedite, Hasten, and Hurry. All three given words describe the act of making something happen more quickly or speeding up a process.
Step 2: Check each option against this meaning. Accelerate means to increase the speed of something or make it happen sooner, which matches the group perfectly. Retard means to slow down, which is the opposite. Provide means to supply something, and Disable means to make something non-functional; neither relates to speed.
Step 3: Since Accelerate shares the same core meaning of speeding something up as Expedite, Hasten, and Hurry, it is the correct synonym.
Final Answer: Option (A) Accelerate.
