Foreign key related to which of the following DBMS constraint?

Read the passages carefully and choose the best answer to each question out of the four alternatives.Keeping employees happy, motivated, and on the payroll is one of the key concerns to businesses these days because its an open market for top talent. A good employee can walk out of the door today and have a comparable or better job tomorrow. Which brings up a very important question: what would the companies do to keep away that person from even thinking about going to work elsewhere? Gone are the days when the monthly paycheck and two weeks vacation a year were enough to keep employees happy. Employers must come up with irresistible incentives to keep top talent on board. The results of a recent survey by Fortune Magazine on why people leave their jobs shows that 30 per cent leave for better compensation and benefits, 27 per cent for a better career opportunity, 27 per cent for new experience, 21 per cent are dissatisfied with opportunities at current job, and 16 per cent desire to change careers or industries. Money is no longer the only major motivator. So, is this an onsite daycare centre for working parents? Paying for all or part of their health insurance? Or offering educational assistance or paying for certification? On an annual ski trip, paid foreign tours, onsite car washes and oil changes? Or free laundry and dry cleaning facilities? Or prized stock options? Well, it could be anything as long as it can keep the employees motivated. There are perks other than monetary gains or raise in pay package which can make employees feel happy and satisfied and the feel-good factor.Q. Which of the following reason is not being mentioned in the passage in regard to people leaving their jobs?
