Topic: Voice, Subject: English Grammar (ইংরেজি গ্রামার)

Best Answer Explained in Below-:

The original sentence "He dispensed with my services" is in the active voice and indicates that someone has decided no longer to use or require your services. To convert this sentence into the passive voice, we need to focus on the structure and the correct form of the verb.

Option A, "My services was dispensed by him," is incorrect because "services" is plural, so it should use "were" instead of "was." Option B, "My services were dispensed by him," also fails to capture the original meaning because "dispensed" alone does not convey the sense of termination implied by "dispensed with."

Option D, "My services were dispensed at by him," is incorrect due to the use of "at," which misrepresents the relationship between the subject and the action.

Option C, "My services were dispensed with by him," is correct because it maintains the original meaning while following passive voice construction. It uses "were" to agree with the plural noun "services" and preserves the prepositional phrase "with" to reflect the original context of ending the need for the services. Therefore, Option C effectively conveys the intended message in passive voice.
