Fill in the blank with the correct article in the sentence given below:
Lavanya's father requires _____ X-ray of his chest to be done immediately.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → an
Complete sentence: Lavanya's father requires an X-ray of his chest to be done immediately. The letter X is read "eks". It begins with the vowel sound "e", so it takes an: an X-ray.
| Option | When to use | Example |
|---|---|---|
| (1) a | "A" goes before a consonant sound. X-ray begins with the vowel sound "e". | – |
| (2) an (answer) | The choice depends on the first sound: an before a vowel sound, a before a consonant sound. One X-ray, not a particular one already known, so the indefinite article is right. | She bought an LED bulb. |
| (3) the | "The" would mean a particular X-ray already known. The father needs one to be done, not a specific one already mentioned. | – |
| (4) no article | "X-ray" here is a singular countable noun and needs an article. | – |
