Concept:The precautionary motive for holding money means keeping cash aside to meet unexpected or emergency expenses.
Explanation:People hold money not only for daily needs or future investment, but also as a safety buffer.
This buffer is used when sudden, unplanned events occur, such as illness, accidents, or urgent repairs.
These events cannot be predicted in advance, so a person must have cash readily available to handle them.
Option A refers to the transaction motive, which covers regular daily purchases.
Option B refers to the speculative motive, which involves holding money to take advantage of expected price changes.
Option D is a planned expense, so it is not an unforeseen event.
Thus, the precautionary motive is specifically for unforeseen events.
Answer:C. Cover unforeseen events.
