From the figure given
The point ABC has a coordinate point of (0, 4)
The triangle DEF has a coordinate point of (5, 8)
From the original triangle, there is a dilation by a scale of factor 2 to give a triange DEF
That is (0, 4)
(0 x 2, 4 x 2)
(0, 8)
Followed by a translation of (x + 5, y)
(0 + 5, 8)
(5, 8)
The answer is option B
