Which category of aircraft includes Normal, Utility, and Acrobatic?

The correct category of aircraft that includes Normal, Utility, and Acrobatic is best described as "Airplane." This category is defined by the Federal Aviation Administration (FAA) and encompasses various aircraft types suitable for different operational limits and purposes.

Normal category aircraft are intended for general aviation use and are designed to withstand a certain level of aerodynamic loads without structural damage. Utility category aircraft have increased load factors and are authorized for maneuvers such as spins and gentle aerobatics. Acrobatic category aircraft are specifically designed for aerobatic flight, allowing for more extreme maneuvers.

While "Transport" generally refers to larger aircraft engineered for the commercial transport of passengers and cargo, this does not adequately cover the specifications or operational capabilities of Normal, Utility, or Acrobatic aircraft. Each of these categories has unique structural limits and design features that are specifically found within the Airplane category, making it the appropriate choice for this question.
