  • The spores are asexual reproductive bodies.
  • Each tiny spore is covered by a hard protective coat to withstand unfavourable conditions such as high temperature and low humidity. So they can survive for a long time.
  • Under favourable conditions, a spore germinates and develops into a new individual. Plants such as moss and ferns also reproduce by means of spores.
  • Thus, Option "A" is correct.
