D. $7$

Answer 1

Hint:
If we know the definition of matter, then we can differentiate between matter and the non-matter. Matter is something that has space and can occupy space, which can be touched.

Complete step by step solution
We already know what is matter, something which occupies space and has mass is called matter. There are different states of matter solid, liquid and gas. Fourth and fifth states of matter are plasma and Bose Einstein condensed state. The object which we can touch matter. The emotions we cannot touch but we can feel.
We can easily pick the matter from the list given in the question. Chair is the matter as it can be classified as solid. Air is classified into gaseous state. Heat is the form of energy so it cannot be classified as matter. Smell is not classified as matter. Sound is the form of vibration so it is not classified as matter, Almond is solid food so it can be classified as matter. Thoughts do not consist of particles or occupy space so it does not matter. Cold drink is a liquid hence it is a matter.

Hence, the matters from the given list are: Chair, Air, Almonds, and Cold drink. So we can say that the correct option is (A).

Note:
The sixth state of matter is being found by scientists known as Fermionic Condensate, which is used to transmit electricity.
