Answer 1

I can't reliably read the four choices from the text you pasted — the formatting looks garbled. Could you retype the four options exactly (or paste a picture)?

Meanwhile, a couple quick notes that may answer it depending on what you meant:
- Any repeating decimal (like -1.232323... = -1.\overline{23}) or any fraction (like 2/3 or 8/8) is rational.
- 0 is rational.
- Common irrational examples are √2, √3, π, e (non‑terminating, non‑repeating decimals).

So if your option C was √2 (or √3, or π, etc.), that option is the irrational one. If the options really were -1.\overline{23}, 8/8, 2/3, and 0, then none of them is irrational. Please repost the choices clearly and I’ll pick the correct one.
