• Difficulty in initiating movements, along with tremors and stiffness
• Sudden loss of muscle control leading to falls, and memory loss
• Rapid deterioration of cognitive functions and loss of balance
• Rapid, involuntary movements primarily in the hands and feet

  The correct answer is: Difficulty in initiating movements, along with tremors and stiffness   Explanation: Parkinson's disease is characterized by the following hallmark symptoms:

• Bradykinesia (difficulty initiating and performing movements)
• Resting tremor (typically seen in the hands or fingers)
• Muscle rigidity (stiffness in the limbs and trunk)
• Postural instability (difficulty maintaining balance, leading to falls).

  These symptoms are due to a loss of dopaminergic neurons in the brain, particularly in the substantia nigra. Cognitive decline can occur later, but the primary symptoms are motor-related.
