Correct option is C. (i) and (ii)
  • The sporangium of bread mould releases a large number of spores that germinate on a suitable substratum to form the hyphae.
  • Multiple hyphe branch and entangle to form a mat like structure called the mycelium.
  • Fungi are saprophytes. Therefore, profuse growth is only possible in presence of a suitable substratum that supplies large amount of moisture and nutrients, like bread.
So, the correct answer is '(i) and (ii)'
