a. Product, price, distribution, and promotion variables

Explanation:

As a customer requires various attributes of the product, that is for which the customer will not compromise in, these include:

The product needed, as for the customer is hungry he shall ask for a pizza, now pizza is a product.

The price of the product, if the price is in the budget of the customer he shall buy it else he shall not buy it.

Distribution associated with it basically the method in which it will be distributed, the packaging extracts.

Promotion variables includes extra benefits like offered with the product, cash backs as for example, etc:

cognitive overload: having a lot on your mind impairs decision-making and tends to result in the simplest, but not necessarily best, option being selected.

empathy gaps: overlooking how you might feel in a different situation can result in unnecessary purchases, such as overbuying when shopping for food on an empty stomach.

optimism and overconfidence: wearing rose-tinted glasses and having unrealistic expectations about the future can affect money management and leave you unprepared for a change in circumstance.

instant gratification: seeking instant gratification drives impulsive spending and can undermine long-term planning and savings.

harmful habits: automatic or mindless behaviour can amplify a poor financial decision as it becomes a recurring event.

social norms: we are heavily influenced by the actions of others; while this can be in certain circumstances, it also contributes to the pressure to keep up with the joneses through conspicuous consumption.
