C ) Spines n tails

D ) Hatch n lay eggs

Answer 1

The option that applies only to embryos (rebros) rather than adults is:

A) Gill slits that turn into gills

In many vertebrate embryos, including those of fish and reptiles, gill slits are present during early development. However, in reptiles, these structures do not develop into functional gills in adults, as reptiles do not use gills for respiration. Instead, they develop lungs for breathing.
