L,
 
Lichens are the first species that appear after primary succession. During secondary succession and also during the transition phase, grasses and shrubs appear. Perennials are not the components of these stages of succession and usually not present during primary succession. Answer for 1 is a since pioneer species are the first to appear after  primary succession
 
I hope this helps.
