निम्नलिखित में से कौन सा अमान्य सेल पता है?
Which of the following is invalid cell address?
A
A1
B
Z249
C
71A
D
M54
Explanation
The correct answer is:
(C) 71A
In spreadsheet software like Excel or LibreOffice Calc, a valid cell address consists of a letter (representing the column) followed by a number (representing the row). In this case, "71A" is invalid because it does not follow the correct format. The column must be represented by a letter (A-Z), and the row by a number (1, 2, 3,...).
Correct Answer: C) 71A
