The correct answer is 'fully'.We know that when 'fully' is added before 'aware' only then it makes that meaningful word.Fully Aware: knowing that something exists, or having knowledge or experience of a particular thing. Example: He is fully aware of our business. Therefore, the correct answer is Option 2. Correct Answer: fully.We tend to go for other options but it would be wrong because when we can 'rightly, nearly, or exactly' they don't make any meaningful word. Therefore, the correct answer is Option 2.
