Answer

(2) A, B, C and E only

Solution

In all connective tissues except blood, the cells secrete fibres of structural proteins called collagen or elastin.

Blood is a fluid connective tissue without such fibres.

So the fibres are secreted in cartilage, bone, adipose tissue and areolar tissue: A, B, C and E.
