Given below are two statements:- Statement I: The nose contains mucus – coated receptors which are specialised for receiving the sense of smell and are called olfactory receptors. Statement II: Wall of the eye ball has three layers. The external layer is called choroid (dense connective tissue), middle layer is sclera (thin pigmented layer) and internal layer is retina (ganglion cells, bipolar cells and photoreceptor cells). In the light of the above statements, choose the correct answer from the options given below:
A
Statement I is true but statement II is false
B
Statement I is false but Statement II is true
C
Both Statement I and Statement II are true
D
Both Statement I and Statement II are false.
Detailed Solution
Statement I correctly describes olfactory receptors in the nose. Statement II incorrectly swaps the names/descriptions of the eyeball's layers: the external layer is actually the sclera (dense connective tissue), and the middle layer is the choroid (thin, pigmented, vascular layer) — the layers given are reversed, so Statement II is false.
