The correct option is C Snow leopard
Excess of greenhouse gases in the atmosphere like carbon dioxide, methane, chlorofluorocarbons etc., lead to global warming. Global warming will lead to melting of ice caps and melting of glaciers. Consequently, animals living at high altitudes or in frozen areas will face the threat to survival. Hence snow leopards which live in the Himalayan region are under threat. Thus, the correct answer is option C.
