The first cell in EXCEL worksheet is labeled as A. AA B. A1 C. Aa D. A0

AA
A1
Aa
A0

The correct answer is B. A1.

A spreadsheet is a grid of cells that can be used to store and organize data. Each cell has a unique address, which is made up of a letter and a number. The first cell in the spreadsheet is always labeled A1.

Option A is incorrect because it is not a valid cell address. Option C is incorrect because it is not a valid cell address. Option D is incorrect because it is not a valid cell address.

I hope this helps! Let me know if you have any other questions.
