(B) To round off a number to a specific number of significant figures,we look at the digit following the last significant figure.Here,we need to round $2.845$ to $3$ significant figures.The first $3$ digits are $2, 8, 4$. The next digit is $5$.According to the rules of rounding off,if the digit to be dropped is $5$ followed by zeros or nothing,and the preceding digit is even,it remains unchanged.Since the digit $4$ is even,$2.845$ rounds to $2.84$.

Round off the value $2.845$ to three significant figures.
