The accepted answer is A. A design guideline suggesting that building complex behavior by combining objects is often preferable to relying solely on class inheritance.. In computer science Composition over inheritance refers to which of the following is answered by A design guideline suggesting that building complex behavior by combining objects is often preferable to relying solely on class inheritance option A Option B A variable defined in a class for which each object of that class maintains its own separate copy does not match the stem it is a near-miss used to catch incomplete recall of A design guideline suggesting that building complex behavior by combining objects is often preferable to relying solely on class inheritance Option C A mechanism where the method to be executed is determined at compile time based on the object's declared type does not match the stem it is.
- A. A design guideline suggesting that building complex behavior by combining objects is often preferable to relying solely on class inheritance. ✓
