c) they all imposed a single religion and language for the empire.
d) they were powerful states capable of coercing resources from subjects.

Option: d) They were powerful states capable of coercing resources from subjects.

Explanation:

All the classical empires build with powerful states along with the army, which helped them gaining control over small weak states and expand their territories by building greater empires. The empires were famous for persuading others who lost the war by imposing laws to provide resources (taxes and food) in helping to build the empire flourish and prosper.  

the correct answer option is: weapons.

explanation:

tensions rose as the two opposing superpowers competed for 'weapons'.

referring to the cold war (1945-1991), the two superpowers, usa and ussr, experienced a phase of struggle and conflict with each other. these two superpowers considered each other as a threat to their survival and thus opted for policies to strengthen their positions.

the two superpowers never went to war with each other directly but competed for weapons to preserve their positions.
