The question of abolition of private property is still a moot point. A. undecided B. uncertain C. unknown D. not clear

The correct answer is A. undecided.

A moot point is a point that is no longer open to debate or discussion because it is clear what the answer is. In the context of the question, the abolition of private property is a point that is still being debated and discussed, so it is not yet clear what the answer is.

The other options are incorrect because they do not accurately describe the meaning of the word “moot.” Option B, uncertain, means that there is no clear answer to a question. Option C, unknown, means that there is no information available to answer a question. Option D, not clear, means that it is difficult to understand a question or statement.
