Which statements are true for generics and generic arrays?
    a) At compile time, an unbounded generic type is resolved to type Object. 
    b) When inheriting from a generic superclass, a generic subclass is NOT allowed to use more type parameters than the superclass.
    c) Constraining a type parameter T with an interface IF is implemented as: T extends IF.
    d) Given a type parameter T, an array can be declared and initialized as: T[] myArray = new T[10].
