If a thin slice of sugar beet is placed in concentrated solution of  $\mathrm{NaCl}$  then

Option (a) is correct for the given statement that is when a thin slice of sugar beet is placed in a concentrated solution of $\mathrm{NaCl}$  then sugar beet will lose water from its cell as it undergoes osmosis. The osmosis happens from one of the diluted solution to the concentrated solution i.e., exosmosis.
