Solution

The correct option is B $1, 2, 3$
Activation of an adsorbent means increasing it's adsorbing power by increasing the surface area of the adsorbent by making it's surface rough, by removing already adsorbed gases from it and by subdividing the adsorbent into smaller pieces or grains.

If the number of active centers is high then higher is the adsorption.

If the concentration is very high then the enzymes bring fermentation in fruits early.
If there is a negative catalyst then it decreases the activation energy.

1,2,3 are the correct statements
