Final answer:
Record rainfalls in the 1- to 24-hour range for the United States have often been set in Texas, due to extreme weather events and thunderstorms. Hence, the correct option is A.
Step-by-step explanation:
Many of the United States' and world records rainfalls were established during the time of thunderstorms in Texas. Areas like Texas often experience extreme weather events, leading to records in rainfall.
For example, on June 22, 1947, a thunderstorm near the city of Thrall, Texas, produced a 24-hour rainfall total of 33.0 inches, which remains the record for the most rainfall in 24 hours in the United States. Such thunderstorms contribute to Texas holding many rainfall records.
Hence, Option A is correct.
