Answer:
The correct answer will be option - D.
Explanation:
Slime moulds are the fungus-like protists which bear a structure called sporangium which produces spores.  The sporangium is produced in fungi as well due to which these protists are called fungus-like.  Although both produce sporangium but they are not closely related, rather they are distantly related organisms.
The appearance of a sporangium in both indicates that they had faced the same conditions due to which they both showed the same adaptation by producing the same structures performing the same function. In evolutionary terms, this is an example of convergent evolution.
Thus, option D is the correct answer.
