What they are really asking
This is a factual question, but it often hides a second one. If your resume shows an end date, or no end date, the interviewer wants to know whether you're working now and, if not, what you've been doing. They're checking the gap. A gap isn't a problem in itself. People get laid off, care for family, study, travel, recover from illness. What makes a gap look bad is a vague or nervous answer.
Answer the question directly first, then explain briefly. If you're still employed, say so and add a line about your notice period if it's useful. If you've left, give the month, one honest sentence about why, and what you've been doing since.
A shape that works
Yes or no, reason, what now. Give the direct answer in the first sentence. Add one calm sentence of explanation. Then describe what you've been doing, especially anything that keeps your skills current: courses, freelance work, volunteering. If the reason was a layoff or restructuring, say so; it's common and doesn't reflect on you.
