The connection between them is Vitamin D.
Vitamin D can be obtained from food and supplements, or synthesized by our bodies when we receive UV radiation in our skin, which is our major source. However, this vitamin comes <span>inactivated</span> and the only way to activate it is through enzymatic conversion (hydroxylation) in the liver and later in the kidneys.
This vitamin is necessary in the intestines because allows calcium and phosphorus to be observed, leading to normal growth and development of bones and teeth. Without enough vit D, bones become fragile, causing osteoporosis.

A. spiral galaxies are not pinwheel-shaped
Explanation:
There are three types of galaxies that include spiral galaxy, elliptical galaxy and irregular galaxy.
Elliptical galaxies are round shaped as well as elongated. Elliptical galaxies have both old and new stars but mostly it contains old stars.
Spiral galaxies are pinwheel-shaped due to the regular spinning motion of dust, stars and gas around the galactic center, at speeds of hundreds of kilometers per second which allows the matter to take a pinwheel-shape. Spiral galaxies are made up of lot of gas and dust and forms many new stars which allows the spiral galaxy to shine bright.
Irregular galaxies do not have any definite shape because of the gravitational influence of close galaxies. They also have many new stars.
Hence, the error is foudn in first sentence, where it says that spiral galaxies are not pinwheel shaped. so teh correct option is A.
