Answer: The answer is (A). always.
Step-by-step explanation: The given statement is -
"A line parallel to one side of a triangle, and intersects the other two sides, divides the other two sides proportionally."
We are to check whether the given statement is always true, sometimes true or never true.
Triangle Proportionality Theorem states that if a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally.
Thus, considering the above theorem, we can conclude that the given statement is always true.
Thus, (A) is the correct option.
