Explanation / Answer

Question 11:

Answer: c) Martha

Employee e1 object name is Sally

Employee e2 object name is Jane

When we use this statement e2 = e1, all properties of e1 is assigned with e2. So when we do any modification on e2 object that will reflect in e1 objet as well. So we set e2 object name as "Martha" so when we use this sttaement e1.getName() that will return "Martha".
