Big Book T27-S1-Q6

Please help me on this question. I need logical explanation and the strategy applied on this question.

The painting was larger than it appeared to be, for, hanging in a darkened recess of the chapel, it was ------- by the perspective.
(A) improved
(B) aggrandized
(C) embellished
(D) jeopardized
(E) diminished

Taking ‘for’ as support, idea 1 would be “The painting was larger than it appeared to be” which means the painting looked smaller than its actual size.

For Idea 2 to be the same, the blank should be something like “smaller”. Thus, E) Diminished

Now I got it. Thanks Man.
