What sentence is known for containing every letter of the alphabet?

The sentence "The quick brown fox jumps over the lazy dog" is a well-known pangram, which is a phrase that includes every letter of the alphabet at least once. This characteristic makes it particularly useful for testing fonts and keyboard layouts, as it allows one to see each letter in use within a complete sentence. The sentence's construction ensures that it not only contains all 26 letters of the English alphabet but does so in a coherent and somewhat whimsical manner, capturing a vivid image that many people find familiar.

In contrast, the other options do not contain every letter. For example, "A journey of a thousand miles begins with a single step," lacks several letters, including 'v' and 'x'. Similarly, "To be or not to be, that is the question" and "All roads lead to Rome" also do not meet the criteria for a pangram, missing various letters from the alphabet. Thus, the choice of "The quick brown fox jumps over the lazy dog" is uniquely relevant as it serves the essential function of demonstrating the complete set of alphabet letters.
