Question

isabelle needs to select cells a2, c2 and d2, and change them to the currency format. which key does isabelle need to press and hold while selecting the cells so she can format all of the cells at one time?
a ctrl
b tab
c alt
d shift

Explanation:

In spreadsheet software, holding the CTRL key allows selecting non-adjacent cells (like A2, C2, D2) simultaneously for bulk formatting. TAB moves between adjacent cells, ALT accesses menu shortcuts, and SHIFT selects a continuous range—none of these fit non-adjacent selection here.

Answer:

A. CTRL
