Answer 1

The correct option is B X $\to$ Vulnerable species

Y $\to$ Rare species
Z $\to$ Endangered species

• Vulnerable species are those species whose numbers are very low and continues to decline rapidly. Lions and tigers are examples of vulnerable species.
• Rare species are endemic to a region. Their numbers are rapidly declining and are extremely prone to extinction. Red panda and musk deer are two examples of rare species.
• Endangered species are those species whose numbers have declined to such an extent that they will become extinct in the near future. Lions and tigers are examples of endangered species.
