The maximum number of Columns in a worksheet in MS-Excel are

The correct answer is (d) 16,384.

A worksheet in MS-Excel is a grid of 16,384 columns and 1,048,576 rows. Each column is identified by a letter, starting with A and ending with XFD. The first 26 columns (A-Z) are standard columns, while the remaining 16,358 columns (AA-XFD) are extended columns.

Extended columns are used to store large amounts of data. They are also used to create custom functions and macros.

To insert an extended column, right-click on the column header and select Insert. To delete an extended column, right-click on the column header and select Delete.

I hope this helps!
