Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. my research rely at phone calls.
The error in the given sentence is in the second part, "my research rely at phone calls." The preposition "at" should be replaced with "on". So, the correct sentence would be "Most of the families in my research rely on phone calls for almost all of their communication."
The correct usage is "rely on" instead of "rely at" as "rely on" means to depend on or trust someone or something. Hence, it is important to use the correct preposition to ensure grammatical accuracy.
