C Correct answer
Explanation

The assertion is true - tracheids are the main water-conducting cells in Gymnosperms since they lack vessels. The reason is false - tracheids are dead at maturity with lignified walls, though they may contain protoplasm during early development. The statement that they are living cells is incorrect. Thus, C is the right answer.
