Solution

The correct option is A 5/6, 6/7, 7/8 and 8/9
Spermatheca is pear shaped internal sacs, which receive and store sperm during the process of copulation. There are four pairs of spermatheca present in an earthworm in the 5/6, 6/7 7/8 and 8/9 segments. The spermatheca opens externally by four pairs of separate spermathecal pores lying ventrolaterally in the grooves between 5/6, 6/7, 7/8 and 8/9 segments. Thus, the correct answer is option A.
