D. basic to math but not to science.

Is D the correct answer

No.

No, A

No, the correct answer is A. Concepts can be characterized as the building blocks of knowledge. Concepts are mental representations or categories that we use to understand and organize information about the world. They are not specific to any particular subject such as math or science.

To determine if option D is the correct answer for the question, "Concepts can be characterized as:", let's first understand the meaning of the given options:

A. the building blocks of knowledge: This option suggests that concepts are the fundamental components upon which knowledge is built.

B. thoughts that are incomplete until adulthood: This option implies that concepts are not fully developed until a person reaches adulthood.

C. ideas that young children do not yet have: This option states that young children do not possess or understand concepts.

D. basic to math but not to science: This option suggests that concepts are essential to mathematics but not to science.

Now, considering these options, we can see that option D is not the correct answer. Concepts are not limited only to mathematics; they are fundamental to various fields of knowledge, including both mathematics and science.

Therefore, the correct answer is:
A. the building blocks of knowledge.
