Connective tissues typically have
a) little space between the membranes of adjacent cells
b) the ability to transmit electrochemical impulses
c) the ability to shorten upon stimulation
d) relatively few cells and a large amount of extracellular matrix

D) relatively few cells and a large amount of extracellular matrix

Explanation:

connective tissue are widely spread through out the body and and perform very important function in the body.  Cells in connective tissue are widely spaced i.e there is lot of space in between these cells and cells are not actively touching one another and because of a lot of space between cells, they have large amount of extracellular matrix.
