Answer:
Option B. is correct.
Step-by-step explanation:
"Enlisted" is the correct choice.
Definition: to participate heartily (as in a cause, drive, or crusade)
Examples: They're enlisting volunteers for an experiment.
• We enlisted the services of a professional.
• They enlisted several new recruits.
"Now, most of Magda’s work is commissioned" supports the previous sentence "They hired her to complete projects for them in different cities" in the passage if we replace word commissioned with enlisted.
