The question asks to identify the figure embedded within a larger figure, without allowing rotation. Let's analyze the provided images:

The main figure shows a specific arrangement of shaded and unshaded squares. We need to find which of the options precisely matches a section of this arrangement.

Option 1: This option correctly represents a section found within the main figure. Careful comparison reveals an exact match of shaded and unshaded square patterns in a specific area of the larger image.

Options 2, 3, and 4 do not match any portion of the main figure. They either have different shading patterns or incorrect arrangements of shaded and unshaded squares compared to the larger image. Therefore, these options are eliminated.

Therefore, the correct answer is Option 1. The key to solving this problem is meticulous visual comparison between the options and the main image section by section. The spatial arrangement of the shaded elements is crucial for a precise match. Any slight deviation in the pattern renders the option incorrect.
