Option B, The false statement from the given is, "Students rarely leave out of college because of financial difficulties".

Explanation:

Undergraduate students may open up job opportunities, but certain students may not bear costs. Student loans are not a prime opportunity to fund a university degree, and credit can be a far bigger burden for dropping-out graduates.

It can be a challenge with two reasons not to hold the student loan debt going after leaving: interest and late payments and the effect on credit. Interest and late charges will continue to increase the overall balance owed by student loans over time. When a student who has withdrawn is prepared to handle his debt, he or she may face a tougher challenge than expected.
