Clubbing of income

Clubbing of income If an individual say Mr.X transfers a house property to his wife Mrs.X for an inadequate consideration then Mr.X is considered to be the deemed owner. In the above case If Mrs X, sells the house property and gets capital gains then it should be clubbed in the hands of of Mr X. My query is that to avail any eligible capital gain exemptions, who has to make investment? Is it Mr X or Mrs X?
