The correct answer is D. Each of these organs is made of tissues composed of different kinds of specialized cells.

Explanation:

An organ is a group of tissues (similar cells organized) that have the same or similar functions, a specific structure and that compose different organ systems or body systems, for example, the stomach and intestines are part of the digestive system. This means all organs including skin, bones, muscles, heart, intestines an any other is composed of a group of cells organized that create tissues. However, the type of tissues and cells in each organ varies as each organ has a different function and therefore it requires specialized cells and tissues to accomplish this function. Thus, the statement that is true about skin, bones, muscles, the heart, and the intestines is that each of these organs is made of tissues composed of different kinds of specialized cells.
