|A) I am very happy to start this Program||B) I am too happy to start this Program|
|C) Both A & B||D) None|
Here I am very happy to start this Program is correct statement.
"Too" is not used with pleasant adjectives. It means 'more than required' and is usually used with unpleasant adjectives.
So, 'too healthy', 'too happy', 'too glad' etc are wrong.
