Select the option that expresses the given sentence in direct speech.
"Mrs. Lisa suggested that we should purchase the property."

Explanation of the Correct Answer:
· In indirect speech, "suggested that we should purchase" conveys a suggestion or proposal.
· The direct speech equivalent of a suggestion uses "Let us" or "Let's."
· Thus, "Mrs. Lisa said, 'Let us purchase the property.'” is the correct answer.
Other options:
· (b) "Property must be purchased by us." → Incorrect because "must" changes the tone from a suggestion to a command.
· (c) "You may purchase the property." → Incorrect because "may" implies permission rather than suggestion.
· (d) "Please purchase the property." → Incorrect because "please" indicates a request, not a suggestion.
Thus, the correct answer is (a) "Let us purchase the property."
