This question tests the correct usage of prepositions in English, specifically with the verb "deprive". We need to find the preposition that fits naturally and idiomatically in the sentence: "He was deprived ____________ his rights."

Understanding 'Deprived' and Preposition Usage

The verb "deprive" means to prevent someone from having or enjoying something, especially something important or pleasant.

In English, certain verbs are commonly followed by specific prepositions to form set phrases or collocations. The standard and idiomatic usage with "deprive" is "deprive someone of something".

Analyzing the Options

Let's look at the given options and see why "of" is the most appropriate:

• Option 1: with - "Deprived with" is not a standard English idiom. Using "with" would suggest being supplied or accompanied by something, which is the opposite of the intended meaning. Example: "He was supplied with his rights."
• Option 2: from - "Deprived from" is sometimes used informally, but it is not considered grammatically correct in standard English. "From" usually indicates separation or origin. Example: "He is suffering from a disease."
• Option 3: of - This is the correct preposition. The phrase "deprive someone of something" means to take away something valuable from them. This perfectly matches the context of being denied one's rights. Example: "The war deprived many people of their homes."
• Option 4: by - "Deprived by" usually indicates the agent causing the deprivation, not the thing that is lost. Example: "He was deprived by the new law." (The law did the depriving).

Conclusion on Rights Deprivation

When discussing the loss or denial of rights, the correct and standard phrasing is to be "deprived of" those rights. The sentence structure implies that the rights were taken away from the person.

Therefore, the complete and correct sentence is: "He was deprived of his rights."
