Classification Of Animals

p (Lacks Jaw) refers to Agnatha, which are jawless vertebrates (e.g., lampreys and hagfish).

q (Bears Jaw) refers to Gnathostomata, which are jawed vertebrates (e.g., fish, amphibians, reptiles, birds, and mammals).

r (Bear fins) refers to Pisces, which are fish (aquatic vertebrates with fins).

s (Bear limbs) refers to Tetrapoda, which are vertebrates that have four limbs (e.g., amphibians, reptiles, birds, and mammals).

The correct answer is (A) :p-Agnatha, q- Gnathostomata, r-Pisces, s-Tetrapoda

The correct pairing is Musa domestica (banana) with Diptera. However, there seems to be some confusion here since Musa domestica belongs to the order Zingiberales, and Diptera is the order for flies. This might be a trick question, or a misinterpretation of the pairing.

The other pairs are incorrect:

• (A) Mangifera indica (mango) belongs to Sapindales, not Primata.
• (B) Triticum aestivum (wheat) belongs to Poales, not Sapindales.
• (D) Homo sapiens (humans) belong to Primata, not Poales.

The correct answer is (C) : Musa, domestica : Diptera.
