Option 3 is the right answer. The given sentence is in the present perfect tense with 'has'. The format should be-- 'have' / 'has' + the past participle. The past participle is made by adding 'ed' to regular verbs [stay-stayed]. So, the sentence should be-- 'has deposited' instead of 'has deposits'. The correct sentence should be--He has deposited all his money in banks.
