The correct answer is Option 4 i.e for James and Lis to live. [ alt="428" src="//storage.googleapis.com/tb-img/production/20/09/428.png" style="width: 40px; height: 40px; float: left;">Explanation: Reading the above sentence we find that: Preposition should be used, if required, after the infinitive, when the infinitive qualifies the noun. In the given statement the preposition "in" should be used after the word "live" i.e to live in. Example: She gave me a pen to write. (wrong) She gave me a pen to write with. (right) Hence from the above points, we find that the correct answer is Option 4 i.e for James and Lis to live and it has an error. The correct sentence is: 'A working party from the church is labouring to make the top two floors of this house habitable for James and Lis to live in.'
