distinguishing inner and outer planets which planet is an inner planet, and which one is an outer planet…

Brief Explanations:

Inner planets (Mercury, Venus, Earth, Mars) are closer to the Sun and generally have shorter days compared to outer planets (Jupiter, Saturn, Uranus, Neptune). Planet A with 16 hours is likely an inner - planet as its day length is relatively short. Planet B with 1408 hours is likely an outer planet as outer planets often have much longer days due to their larger size and slower rotation.

Answer:

Planet A is likely an inner planet. Planet B is likely an outer planet.
