Let me go through these one at a time.

**C1:** **PASS** — the response gives exactly "13,11,7,5,3".
**C2**: FAIL: the digit 2 appears in the explanation text.
c3: pass – five numbers present
C4: FAIL
Some trailing commentary that mentions C1 and C2 again but is not a verdict line.

**SUMMARY:** Mostly right.
