Which of the following statements is not true regarding biological motives?

Biological motives are innate, unlearned physiological drives — hunger, thirst, the need for oxygen, sleep, and temperature regulation — that are common to every member of the species. Their defining function is homeostatic regulation: when a bodily state drifts away from its optimal internal balance (for example, falling energy reserves or dropping fluid levels), the drive activates behaviour aimed at restoring that balance, and it subsides once balance is restored.

The question asks which statement is NOT true about biological motives. Since maintaining internal balance is the very reason biological motives exist, a claim that they are unrelated to homeostasis directly contradicts their defining function, making it the false statement among the four.

• Being common to every member of the species (universal) accurately describes a biological motive — this statement holds.

• Being present from birth rather than learned (inborn) accurately describes a biological motive — this statement holds.

• Driving the organism to secure food, water, oxygen, and safe body temperature (essential to survival) accurately describes a biological motive — this statement holds.

• Claiming no relationship with the maintenance of internal balance is the one statement that does not hold, since restoring that balance is precisely what a biological motive is for.

Hence, the statement denying any connection to homeostasis is the one that is not true.
