If I had a lot of money, __ be ha ppier. I'd I'm I'll

## Step 1<br />The problem is a fill-in-the-blank question that tests your understanding of conditional sentences in English. The sentence is "If I had a lot of money, __ be happier." The blank needs to be filled with a verb form that makes the sentence grammatically correct and meaningful.<br />## Step 2<br />The correct answer is "I'd", which is a contraction of "I would". This is because the sentence is a second conditional sentence, which is used to talk about unreal or improbable situations. The structure of a second conditional sentence is "If + past simple, would + base form of verb".<br />## Step 3<br />In this case, "If I had a lot of money" is an unreal situation (I don't have a lot of money), so the verb that follows should be in the form of "would + base form of verb". Therefore, "I'd" is the correct answer.
