Step 1: Define language isolate
A language isolate is a natural language with no demonstrable genealogical relationship to any other language family. Famous examples: Basque (Spain/France), Ainu (Japan), and Burushashki (Pakistan).
Step 2: Evaluate options
(A) Burushashki — spoken in northern Pakistan (Hunza, Nagar, Yasin valleys). A true language isolate.
(B) Mundari — part of the Austroasiatic (Munda) language family, not an isolate.
(C) Angami — a Tibeto-Burman language spoken in Nagaland, India. Not isolate.
(D) Kalasha — an Indo-Aryan language spoken in Chitral, Pakistan. Related to Dardic languages.
Thus, only Burushashki qualifies as a language isolate.
