Answer
A-Hypertonic and B-Hypotonic
Reason — Water moves from its higher concentration (hypotonic) to its lower concentration (hypertonic) which is called osmosis. In figure A, water is moving out of cell which means the solution is hypertonic. In figure B, water is moving into the cell which means the solution is hypotonic.
