Who defined psychology as "the science of mental life, both of its phenomena and their conditions?"

Correct option is A

William James, an American philosopher and psychologist, defined psychology as "the science of mental life, both of its phenomena and their conditions." This definition reflects his focus on understanding the workings of the mind, including both conscious experiences (phenomena) and the conditions that give rise to them.
Information Booster: William James is often considered one of the founders of modern psychology. His work laid the foundation for functionalism, which focuses on how mental processes function in adaptation to the environment. His book The Principles of Psychology (1890) is a seminal work in the field, where he explores the nature of consciousness, attention, perception, and the conditions that shape mental life.
