II only
c.
I and III
d.

Answer 1

First compute totals:
- September total = 346+297+199+245+225 = 1312
- October total = 308+260+285+186+275 = 1314

I. Cats' market share
- Sept: 199/1312 ≈ 15.18%
- Oct: 285/1314 ≈ 21.69%
- Increase ≈ 21.69% − 15.18% ≈ 6.51 percentage points → about 6.5 pp (True)

II. "Other" percent increase
- (275−225)/225 = 50/225 ≈ 0.2222 → 22.22% more (True)

III. Total sales change
- (1314−1312)/1312 = 2/1312 ≈ 0.00153 ≈ 0.15% increase, not about 2% (False)

Therefore the correct choice is a. I and II.
