A power struggle to control the communist world
Option C.
Step-by-step explanation:
There was a conflict between the Soviet union and China which went on for a period of seven months and it was an undeclared war between the two of them. This was caused because of the difference in the interpretation of Marxism and Leninism.
The result of this conflict between the two in the year 1969 led to the ceasefire with both of them returning to the status quo.
