The correct answer is:
D

I don't see the figure, but we can still reason carefully. Since it's a multiple-choice Boolean expression question, let's analyze the options:

The options are:

1.

2.

3.

4.

Look for common factor
All options have as a factor except option , which is . So, if the circuit has a NOT gate on feeding an AND, it is likely options , , or .

Look at OR combination

Option : AND of with uses De Morgan form.

Option : AND of with mixed negation.

Option : AND of with straightforward OR.

Common Boolean patterns

If the circuit has NOT on A, AND with an OR of B and C → likely option .

If the circuit has NOR style on B and C → likely option .

Without the figure, the safest assumption is that the circuit represents , which is a common AND-OR combination.
