a the official season is april 1 - september 30.
b storm must be a minimum 150 mph wind speed to be considered a hurricane.
c every tropical storm develops into a hurricane.
d they are classified by wind speed.

Explanation:

• Option A: The official hurricane season is June 1 - November 30, not April 1 - September 30, so A is false.
• Option B: A hurricane needs sustained wind speeds of at least 74 mph, not 150 mph, so B is false.
• Option C: Not every tropical storm develops into a hurricane; some may dissipate or remain as tropical storms, so C is false.
• Option D: Hurricanes are classified by their wind speed (e.g., Category 1 - 5 based on wind speed), so D is true.

Answer:

D. They are classified by wind speed.
