पर्याय

• i, iii and iv only

• i, ii and iv only

• i, ii and iii only

• ii and iv only

Answer 1

i, ii and iv only

Explanation:

A stable community can recover quickly from disturbances (i), is resistant to invasive species (ii), and has high species diversity (iv), which increases stability. However, biomass production is not constantly changing in a stable community, so statement (iii) is incorrect.
