Final answer:
The value of the variable s2 is "quick" as it is the second word in the array created by splitting the original string s1 by spaces.
Step-by-step explanation:
The value of the variable named s2 after the given statements have been executed is "quick". The strings are split by spaces using the Split method, which creates an array of words from the original string s1. The phrase "The quick brown fox" when split by spaces results in an array where "The" is at index 0, "quick" is at index 1, "brown" is at index 2, and "fox" is at index 3. Therefore, s2 is assigned the value of the word at index 1, which is "quick".
