I have been asked this question by my school principal while I was bunking the class.

Answer 1

Right option is (a) A technique of C++ that allows us to write inline functions without a name

Easy explanation - Lambda expression is a technique available in C++ that helps the programmer to write inline functions that will be used once in a program and so there is no need of providing names top them. Hence they are a type of inline functions without names.
