1a Ans is Option C When one solution have higher concentration of solute than the other solution then the solution with higher conc is known as hypertonic and the solution with lower conc is known as hypotonic solution In these cases a concentration gradient of solute exist from hypertonic to hypotonic solution When the conc of solute is same in both the solution then the solutions are known as isotonic solution and there is no concentration gradient
