What is the difference between sclerenchyma and collenchyma?

Match the column $(A)$ with the column $(B)$:

Column $(A)$	Column $(B)$
$(a)$ Parenchyma	$(i)$ Thin walled,packing cells
$(b)$ Photosynthesis	$(ii)$ Carbon fixation
$(c)$ Aerenchyma	$(iii)$ Localized thickenings
$(d)$ Collenchyma	$(iv)$ Buoyancy
$(e)$ Permanent tissue	$(v)$ Sclerenchyma

Name the following and give one characteristic of each:
$(a)$ Living tissue that provides mechanical support in plants.
$(b)$ Highly specialised cells for being stimulated and then transmitting the stimulus very rapidly within the body of animals.
$(c)$ Animal tissue with elongated cells and contractile proteins responsible for movement.
