[amp_mcq option1=”at a sight or on a demand” option2=”on sight or at demand” option3=”at sight or demand” option4=”No correction required” correct=”option4″]
The correct answer is: D. No correction required.
The phrase “at sight” means “immediately upon presentation.” The phrase “on demand” means “when requested.” In this case, the bill will be paid either immediately upon presentation or when requested. Therefore, the phrase “at sight or on demand” is correct.
Option A, “at a sight or on a demand,” is incorrect because the word “a” is not necessary.
Option B, “on sight or at demand,” is incorrect because the word “at” is not necessary.
Option C, “at sight or demand,” is incorrect because the word “or” is not necessary.
