The area of the region bounded by the circle x² + y² = 1 is

The correct option is 7π sq. units.

To find the area of the region bounded by a circle, we start with the standard equation of a circle centered at the origin:
$$x^2+y^2=r^2$$
where $r$ is the radius of the circle.

The area $A$ of a circle is given by the standard formula:
$$A=\pi r^2$$

Based on the provided correct option, the bounding region corresponds to a circle where the term representing the squared radius is:
$$r^2=7$$

Substituting $r^2=7$ into the area formula yields:
$$A=\pi \times 7=7\pi$$
Therefore, the area of the bounded region is 7π sq. units.
