abcdefghijklmnopqrstuvwxyz riddle: Which sentence contains all the letters from a to z at least once?

Introduction / Context:
This puzzle is about pangrams, which are sentences that use every letter of the alphabet at least once. Pangrams are popular for testing typewriters, fonts and keyboards because they touch all letters from a to z. The most famous English pangram is The quick brown fox jumps over the lazy dog, and this riddle checks whether you recognise that sentence and understand the concept of a pangram.

Given Data / Assumptions:

• The question mentions the full lowercase alphabet sequence abcdefghijklmnopqrstuvwxyz.
• It then asks which sentence contains all letters from a to z.
• Options include several common sayings and the very well known fox sentence.
• We assume standard modern English spelling.

Concept / Approach:
A pangram must include each of the 26 letters at least one time. The sentence The quick brown fox jumps over the lazy dog is widely used for this purpose and is known to contain every letter. The other options are everyday proverbs and phrases, none of which are designed specifically as pangrams. Instead of counting every letter manually, we can rely on the established role of the fox sentence in typography and language practice.

Step-by-Step Solution:
Step 1: Recall the definition of a pangram: a sentence that uses all letters a through z at least once. Step 2: Recognise that The quick brown fox jumps over the lazy dog is the standard example found in textbooks, software demos and type tests. Step 3: Consider whether the other sentences are famous for being pangrams. They are not; they are just common proverbs. Step 4: If desired, quickly scan The quick brown fox jumps over the lazy dog and notice unusual letters like q, x, j and z all appearing. Step 5: Try scanning A watched pot never boils or Better late than never and see that they do not contain rare letters like q, x or z. Step 6: Based on knowledge and quick checking, confirm that option A is the pangram that covers the entire alphabet.

Verification / Alternative check:
To verify more systematically, you could list letters from a to z and mark each as you find it in the fox sentence. You would eventually mark all 26 letters. Performing the same process on the other sentences would leave several letters unchecked, especially q, x and z. Because the riddle asks specifically for a sentence containing all letters, only the fox sentence qualifies, matching the knowledge that it is a classic pangram used in print and design work worldwide.

Why Other Options Are Wrong:
A watched pot never boils: This contains common letters but lacks rare ones such as q and x.
Better late than never: It is a proverb about patience, not designed to be a pangram, and misses several alphabet letters.
Practice makes perfect: This phrase also lacks some letters and is not known as a pangram.
None of these: This is incorrect because one of the listed sentences is a well known pangram.

Common Pitfalls:
Some learners may overthink and suspect that the question is a trick, leading them to choose None of these. Others may not be familiar with the term pangram and therefore treat all sentences as equal. It helps to remember certain famous reference sentences, such as The quick brown fox jumps over the lazy dog, which appear frequently in computer interfaces, font previews and language exercises. Recognising them quickly saves time in test situations.

Final Answer:
The sentence that contains all letters from a to z is The quick brown fox jumps over the lazy dog.
