You show and answer for this questions on test 351.13 as 11 degrees EAST.
I believe your answer is incorrect for the following reason.
If the vessel is in line with the range marker lights then according to the chart the vessel is heading at 212 degrees TRUE. With a variation of 7 degrees W, the vessel’s standard compass heading should read (212 – 7) or 205 degrees magnetic. However, according to your question his compass is reading 208 degrees, an error of 3 degrees of deviation from what his compass should read with 0 deviation.

I believe the correct answer should be the deviation is 3 degrees E
The multiple choice you supplied were:
A) 4 degrees E
B) 4 degrees W
C) 11 degrees E
D) 11 degrees W
I believe none of your supplied answers are correct.
Can you provide an explanation?
