If __ rich, I would have retired and bought an island. am getting to get had gotten

## Step 1<br />The problem is a test of understanding the correct use of verb tenses in English, specifically the third conditional form. The third conditional form is used to express a hypothetical situation in the past and its probable result in the present or future. The structure of the third conditional form is: "If + past perfect, would have + past participle".<br /><br />## Step 2<br />In the given sentence, "If rich, I would have retired and bought an island", the verb tense is missing. We need to fill in the blank with the correct verb tense.<br /><br />## Step 3<br />Looking at the options, "am getting" is in the present continuous tense, "to get" is in the infinitive form, and "had gotten" is in the past perfect tense. <br /><br />## Step 4<br />The correct verb tense to use in this context is the past perfect tense, which is "had gotten". This is because the sentence is talking about a hypothetical situation in the past, and its probable result in the present or future.
