Integrated drive generators (IDG) employ a type of generator that utilizes?

A single-phase system

A brushless system to produce current

Integrated drive generators (IDGs) in aircraft employ a brushless system to produce current. This technology eliminates the need for brushes, which reduces maintenance requirements due to fewer parts subject to wear and tear. Brushless systems also tend to be more efficient and reliable compared to systems that use brushes. Therefore, option B is the correct answer.

Options A, C, and D are not correct because IDGs typically do not utilize a single-phase system, a direct current (DC) system, or require manual operation for generating current.
