ASSERTION: cartilage (protein matrix) and bone (calcium matrix) are rigid connective
je.
SON: Blood is connective tissue in which plasma is the matrix.
(a) Both assertion and reason are correct and reason is the correct explanation of
assertion.
(b) Both assertion and reason are correct but reason is not the correct explanation
of assertion.
(c) Assertion is correct and reason is incorrect.
(d) Assertion is incorrect and reason is correct.​

Answer 1

Explanation:

The nature of matrix differs depending on the function of the connective tissue. Therefore, matrix plays a key role in the properties of the connective tissue.

Cartilage has widely spaced cells, which are interspersed in matrix made of proteins and sugars.

Bone cells are embedded in hard matrix, which is made up of salts of calcium and phosphate.

Both, cartilage and bone have rigid, stiff extracellular matrix.

Blood consists of fluid or liquid matrix called plasma in which white blood cells, red blood cells and platelets are suspended.

Though both statements are correct, the 2nd statement is not the correct reason for the 1st statement.

Hence the correct option is B.
