What was the length in feet of the longest recorded Blue Whale?
Explanation and memory cue
Authoritative sources such as NOAA and National Geographic report that the longest recorded blue whales measure about 110 feet in length. While some older or less precise sources may mention lengths up to 115 feet, the most reliable and widely accepted maximum length is approximately 110 feet, making option C (111 feet) the closest and most accurate choice among the given options.
