What caused islam to split into sunni and shia branches? a- the question of how to spread the islamic faith b- the question of who should lead muslims c-the question of muhammad's role as prophet d- the question of whose teachings are in the qur'an

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.
