Concept:A cheque is dishonoured when the bank refuses to make payment for some valid reason.
One common reason is lack of money in the account.
Explanation:The bank will only pay a cheque if the drawer's account has enough money.
When the account balance is less than the cheque amount, the bank returns the cheque unpaid.
This condition is called "insufficient funds".
The other options do not cause dishonour.
Same amount in words and figures is a requirement, not a fault.
General crossing only directs payment through a bank.
A regular signature is acceptable, not a problem.
Answer:B. Insufficient fund.
