AConstructor names do not match class name

BMissing return type in constructors

CConstructors must have different names

DTwo constructors have the same parameter type and count

Step-by-Step Solution

Solution:

Step 1: Check parameter lists
Two constructors have one string parameter each: Book(string title) and Book(string author).
Step 2: Understand overloading rules
Overloading requires different parameter types or counts; these two have identical signatures causing error.
Final Answer:
Two constructors have the same parameter type and count -> Option D
Quick Check:
Parameter signature must differ for overloading [OK]

Quick Trick: Parameter types and counts must differ to overload [OK]
