Answer 1

Right answer is (b) Can be created without calling default constructor

The explanation is: The objects need some constructor to get the memory spaced reserved for those. If the default constructor is not used then we can use some arguments constructor which will reserve the memory for the objects. The objects can be passed with constructor arguments during declaration.
