Final answer:
By solving the anagram found in the question 'So, a man walked into a bar & said, give me this type of beer, & make it a large', it's revealed that the man requested a 'lager', as 'large' is an anagram for 'lager'.
Step-by-step explanation:
The question involves solving an anagram to find out the type of beer the man requested in the statement "So, a man walked into a bar & said, give me this type of beer, & make it a large". An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. In this case, when we look carefully at the anagram and arrange the letters, we find that the answer is hidden in the question itself: "large" is an anagram of the word "lager", which is a type of beer. Therefore, the correct answer to what type of beer the man requested is c) Lager.
