A habitat change may result in the decline of the numbers of a given species. Such species slowly become P. This means that the species are on the verge of becoming Q. Some animals whose number has gone down to critically low levels are called R. A species is considered S when no member of the species is still alive. Which of the following is correct sequence for P, Q, R and S in the above paragraph.

AP – Vulnerable, Q – Endemic, R – Extinct, S – Endangered
BP – Endangered, Q – Vulnerable, R – Threatened, S – Extinct
CP – Vulnerable, Q – Endangered, R – Critically endangered, S – Extinct
DP – Endangered, Q – Critically endangered, R – Extinct, S – Vulnerable
