The examiners' report for this question states:
29% of candidates chose the correct answer C. The mst commonly
chosen answer was D chosen by 29% of candidates. If a fixed mass of
gas is behaving ideally the sum PV/RT gives a constant value. for
both the conditions given in the question
PV/RT =6.418 (if volume of 1dm3 and 0.5 dm3 are assumed.
therefore gas is behaving ideally.

Cambridge and I are both correct. The error is yours, hoay. You
gave the wrong temperature after compression.
Using Cambridge values, nR (before compression) / nR (after
compression) = 1.00, hence the gas is behaving ideally.
In future to avoid typos, you can directly post the online link
to the question and mark scheme, instead of typing out the
question.
