Answer 1

D

Work (brief):
- Sandwich: 0.462 lb = 0.462·16 = 7.392 oz
- Sneaker: 290.87 g = 0.29087 kg → 0.29087·2.20462 = 0.641258 lb = 0.641258·16 = 10.2601 oz
- Pinecone: 0.0000453 ton = 0.0000453·2000 = 0.0906 lb = 0.0906·16 = 1.4496 oz
- Dog collar: 0.246 kg → 0.246·2.20462 = 0.542337 lb = 0.542337·16 = 8.6774 oz

Total ≈ 7.392 + 10.2601 + 1.4496 + 8.6774 = 27.78 oz → choice D.
