In the following question, a sentence is divided into

Solution

In part A: The phrase "demand of office space leasing" is incorrect because "demand of" is not the correct prepositional collocation when referring to economic or market demand. "Demand of" is used when referring to something that is required by someone or something (e.g., "The demand of the job is high commitment.")."Demand for" is used when discussing the need or desire for a product, service, or resource in a market (e.g., "There is high demand for skilled engineers.").Since the sentence discusses the market demand for leasing office space, the correct phrase should be "demand for office space leasing."In part C: The phrase "to be cross 60 million sq.ft." is incorrect. The verb "cross" does not require "be" in this context.Thus, the correct sentence should be:"In India, the demand for office space leasing is expected to cross 60 million sq.ft. this year, out of which, 18% belongs to flex spaces."
