Answer:
The correct answer is:
D) attempting to aid the Slavic nations in the Balkans
Step-by-step explanation:
Options A, B, C are all important examples of British influence and power but these were mostly economic decisions that wanted to enhance and improve the country's trade.
For example, invasion of the Suez canal was done as a result of Egyptian nationalisation as the country feared that the closure of the canal can lead to trading problems. Similarly moving Chinese workers to Malaysia was done out of necessity.
However, providing aid to Slavic nations in Eastern Europe was an important geopolitical decision against Russian power in the region.
