Given list1 = [1, 2, 3] and list2 = [4, 5, 6], what would be the first pair of values printed by the nested for loop 'for i in list1: for j in list2: print(i, j)'?

When a nested for loop is executed, how does the inner loop behave relative to the outer loop?

• The inner loop executes once, then the outer loop completes.

• The inner loop completes all its iterations for each single iteration of the outer loop.

• Both loops execute simultaneously.

• The outer loop completes first, then the inner loop starts.

Given list1 = [1, 2, 3] and list2 = [4, 5, 6], what is the output when 'i' is 1 and 'j' is 4 in the print(i, j) statement?

• 1, 4

• 4, 1
