The correct answer is: B. Electricity Bill
An annuity is a series of equal payments made at regular intervals for a fixed period of time. In this case, the payments are Rs. 2000, and the intervals are one year apart. The payments are made for a fixed period of three years.
An electricity bill is not an annuity because the payments are not equal. The amount of the payment will vary depending on the amount of electricity used. The payments are also not made at regular intervals. The bill is usually due once a month, but the due date may change depending on the billing cycle.
Car payments and mortgage payments are both annuities. Car payments are a series of equal payments made at regular intervals for a fixed period of time. The payments are made to repay the loan that was used to purchase the car. Mortgage payments are a series of equal payments made at regular intervals for a fixed period of time. The payments are made to repay the loan that was used to purchase the house.
In conclusion, the only option that cannot be categorized as an annuity is B. Electricity Bill.
