Two planes intersect in: a. line segment b. line c. point d. ray

Two planes intersect in a line. Hence, the answer is option B.

Explanation:

A line can be defined as the continuous points. We cannot draw a line but we can represent  segment of line. It can be drawn in a plane which is of one dimension. There are lot of intersection between two or more than two lines. For having intersection one must have two lines.

We can draw line in any plane. Plane can be drawn in any dimension. Plane is a single dimensional thing. We can draw many lines in a plane in any dimension. Generally all the dimension are represented by x y and z.

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
