Final answer:
The statement is b. false; in McClelland's theory, the need for achievement - not the need for power - is the motivation to excel and achieve in relation to standards.
Step-by-step explanation:
The statement in question, 'the need for power is the drive to excel, and to achieve in relation to a set of standards,' is b. false.
In McClelland's theory of needs, it's not the need for power but rather the need for achievement that motivates an individual to excel and achieve in relation to a set of standards.
The need for power, as defined by McClelland, is the desire to have control or influence over others, which is different from the personal drive aimed at excelling.
McClelland's theory identifies three distinct needs that motivate individuals: the need for achievement, the need for affiliation, and the need for power.
While the need for achievement involves setting and accomplishing challenging goals, the need for affiliation concerns forming relationships and the need for power is about having influence and making an impact on others.
These motives are central to understanding how individuals are driven to act in various personal and professional contexts.
