The correct statement is A larger brain allows humans to solve complex problems.
Explanation:
From the ancient time, the human brain has size increased three times. The most probable reason for the evolution of brains is that larger brain allows humans to handle complex problems more easily.
complex and large brains help humans to understand and store a different type of knowledge and information and aids in interacting with each other.
