Which of these was a concern of mrs. bennet?

Answer 1

Mrs Bennet is afraid Mr Bennet will die before any of her daughters is married.

The problem is that Mr Bennet's estate is entailed, which is to say it must pass to a male heir. Since there is no son in the Bennet family, the estate is to be inherited by Mr Collins, a cousin.

A woman in such a position, who is of the gentility, was expected to work for a living only as a last resort. The position of governess might be open to an educated poor woman of such a class, but the Bennet girls are not highly educated. Their only two options seem to be to marry or to become dependent on some wealthy relative, such as the Gardiners.

Unfortunately, their prospects for marriage are not very great. They have no dowry, unlike Mary King or Georgiana Darcy. Also, as girls coming of age during the Napoleonic Wars, they face stiff competition for men because many young men have gone off to war (a point not explicitly made in the novel, but about a quarter to a third of all the young women would never marry).

If the girls cannot marry before Mr. Bennet dies, they will be poor and unable to attract husbands.

Answer 2

Mrs. Bennet's main concern in Jane Austen's "Pride and Prejudice" was finding suitable husbands for her five daughters to secure their future financial stability and social status. She was preoccupied with making advantageous marriage matches for them, particularly with wealthy and respectable suitors.

Answer 3

That Mr. Bennet would be killed in a fight with Mr. Wickham
