As you were taking lettuce in the grocery store, you were surprised when water sprinklers suddenly went on, spraying fresh water on the produce. When you got back home, you immersed the lettuce in a salt solution, and within several minutes they became limp and soft. What are the explanations for the spraying procedure in the store, and your observation at home?

a) Lettuce cells are hypertonic to fresh water making them turgid and fresh-looking, but hypotonic to the salt solution, hence plasmolyzed.
b) Lettuce cells are hypotonic to fresh water making them turgid and fresh-locking, but hypertonic to the salt solution, hence plasmolyzed.
c) Lettuce cells are isotonic to fresh water making them turgid and fresh-looking, but hypotonic to the salt solution, hence plasmolyzed.
d) Lettuce cells are isotonic to fresh water making them turgid and fresh-looking, but hypertonic to the salt solution, hence plasmolyzed.
