I’m not sure I’m reading the choices correctly — they look misformatted. Two possibilities and the answers for each:
1) If the choices are exactly as printed:
- A = 0.123450.12345 (looks like a repeating block)
- B = 0.750.75 (looks like a repeating block)
- C = 2
All three of those (repeating decimals or an integer) are rational, so none is irrational.
2) If option C was meant to be √2 (the square root symbol got lost) — a very common multiple‑choice — then C (√2) is irrational. Reason: √2 cannot be written as a ratio of integers (classic proof by contradiction: assume √2 = p/q in lowest terms, then both p and q would be even, contradicting lowest terms).
If you can copy the choices exactly as intended (or confirm whether C was √2), I’ll give the definitive answer.
