I suppose it should be a) Code reusability not
removability :)

So the wrong statement is d) program runs faster - c++ is
not faster than say C, pascal or other compiled code (it
has however very good compilers that make very aggressive
optimisations so it may look like it is faster)

a) code reusability - it's true as you can inherit the
class and use its properties and functions again modifying
it to your needs in a derived class

b) encapsulation of data and code - you can declare member
variables (data) and member functions (code) as private,
protected to encapsulate it and forbid its use outside
class instances / instances of inherited classes

c) program easy maintenance - it is true (or at least
should be true) for every oo language. If you are unsure
about this try maintenance large C program
