Concept:
In MS-Excel, formulas always begin with an equal sign. Built-in functions such as SUM, AVERAGE, COUNT, etc. are written using parentheses.
Step 1: Select an empty cell.
First, the user selects the cell where the answer should appear.
\[
\text{First step} = C
\]
Step 2: Type equal sign and function name.
Every Excel formula begins with:
\[
=
\]
For example:
\[
=SUM
\]
\[
\text{Second step} = E
\]
Step 3: Type opening parenthesis.
After the function name, an opening parenthesis is typed.
\[
\text{Third step} = A
\]
Step 4: Select range and close parenthesis.
Then the range of cells is selected and the closing parenthesis is typed.
\[
\text{Fourth step} = D
\]
Step 5: Press Enter.
Finally, pressing Enter gives the result.
\[
\text{Fifth step} = B
\]
Thus, the correct sequence is:
\[
C,\ E,\ A,\ D,\ B
\]
\[
\therefore \text{Correct Answer is (B)}
\]
