The difference in mechanical properties between low density polyethylene and high density polyethylene is due to which of the following? (Choose from the following four possibilities)

		Low density PE has side chains and is amorphous while high density is none branched and can form crystallites
		Low density polyethylene has added plasticizers to reduce density but high density PE does not have added plasticizers
		Low density PE have side chains which enhance crystallite formation, while high density is none branched and amorphous
		None of the above.
