  • A for (i = 0; i < 5; i++) ✔ ✖
  • B for i in range(5) ✔ ✖
  • C for i = 1; i < 5; i++ ✔ ✖
  • D foreach (i in collection) ✔ ✖
Correct Answer: Option B

Explanation

In Python, the for loop syntax uses the in keyword to iterate over an iterable such as a list, tuple, or range. The range(5) generates a sequence of numbers from 0 to 4, and the loop iterates through each number in that sequence. Option A and C are syntax used in languages like Java or C++, and Option D resembles the foreach loop from languages like PHP or C#, but it's not valid in Python.
