To bold the text in MS-Excel 2010 the following shortcut key is used:

Correct option is C

Correct Answer: C) Ctrl + B
Explanation:
· In MS-Excel 2010, the keyboard shortcut Ctrl + B is used to apply or remove bold formatting to the text or numbers in the selected cell(s).
· Bold formatting makes the text thicker and darker, helping it stand out for headers or important data points.
· This same action can also be performed by clicking the 'B' icon in the Font group under the Home tab.
Information Booster:
· Interestingly, MS-Excel also supports Ctrl + 2 as an alternative shortcut to apply or remove bold formatting.
· Keyboard shortcuts like Ctrl + B are known as "toggles." If the text is already bold, pressing the shortcut again will revert it to normal text.
Additional Knowledge:
· Ctrl + I: This shortcut is used to apply or remove Italic formatting, which slants the text to the right. (Alternative: Ctrl + 3).
· Ctrl + X: This is the shortcut for the Cut command. It removes the selected data from its current position and places it on the clipboard to be pasted elsewhere.
· Ctrl + U: This shortcut applies or removes an Underline to the text within the selected cell. (Alternative: Ctrl + 4).
