Q. Which of the following pairs is correctly matched ?

     (a) uricotelism -aquatic habitat

     (b) parasitism- intra-specific relationship

     (c) excessive perspiration -xeric adaptation

     (d) stream lined body-aquatic adaptation 

Dear student,     
Please find below the solution to the asked query                                                             

The correctly matched pair is a streamlined body and aquatic adaptation. Streamlined body is an adaptation observed in aquatic animals like fishes. 

Parasitism is an inter-specific as well as an intra-specific relationship. Uricotelism is not an aquatic adaptation.
Xerophytic plants do not show excessive perspiration. In fact, they prevent excessive water loss.

Hence, option (d) is correct.
