Option: (E)
Explanation:
In order to delve deep down into the investigation to determine whether intelligence is composed of skills and abilities within oneself or is it a single source in itself that serves the development of abilities, the psychologists had to carry out a multifactor analysis.
These factors involved the basic elemental foundation blocks of intelligent behavior exhibited by multiple samples (people).
It was concluded that intelligence is certainly a compound trait of various abilities put to work collectively.
