Question about Multiple choice question in PSM II test

Hi,

In one question in the PSM II about risk for the project, they are 4 answers :
A) lorem ipsum
B) lorem ipsum
C) lorem ipsum
D) lorem ipsum
E) All of the above

I don''t know how the robot read the answer and I want to be sure.

If I want to answer E), do I have to check also A; B; C & D (as it is a multiple choice answer) ? Does it matter for the robot ?
