Why would the age limit for beginning a career as probation or parole officer be cut off at 37?

The suggested reason is that probation and parole work can be demanding, so officers need maturity as well as the energy to manage its pressures. Choice B states this balance directly: mature, but young enough to handle a high-challenge job. The other choices either focus on excluding second-career applicants, oppose age limits, or make a broader claim about people in their thirties.
