Answer & Solution
Correct Answer
(C) Frog has a tail but toad has no tail.
Step-by-step Solution
Detailed explanation
(C) Frog has a tail but toad has no tail.,
The terms "chordata" and "vertebrate" are not synonymous. Chordates are defined by having three key features: a dorsal tubular nerve cord, a rod-like notochord, and pharyngeal gill slits. While vertebrates share these features, they specifically have a vertebral column that replaces the notochord in most adults. However, not all chordates develop into vertebrates, as some retain only the notochord or its remnants.
