A Correct answer
Explanation

Spores are formed inside the sporangia and they are released when the wall breaks. The wall usually breaks on coming in contact with water and seldom on shaking. For release of spores, the lower hyphae or the parent fungus do not break their walls. Thus, (1) is correct.
