Which of the following options correctly represent a formula with absolute references?
a.)=(a$1$-b$1$)
b.)=(a$1-b$1)
c.)=($a1-$b1)
d.)=($a$1-$b$1)

D.)=($A$1-$B$1)

Explanation:

The $ sign placed in between the characters of a cell makes the cell an absolute reference in any formula that involves the cell.

For example, the function "=A1 - $B$2" would give a result equivalent to "=A1 - B2" however, a drag down of the formula would result in a change of the function A1 to A2, A3, A4, A5...

Hence from the options, =($A$1-$B$1) is the only formula with absolute references.

i want to say d but i could be wrong however it is organized if that could happen..

hope it could
