Four extracts were prepared from different plant materials and then tested using Benedict’s solution. Each extract was boiled with Benedict’s solution for $240$ seconds, after which the final colour was noted: extract 1: red; extract 2: yellow; extract 3: blue; extract 4: green. Which sequence of plant extracts shows an increasing amount of reducing sugar?
- A$1 \rightarrow 2 \rightarrow 4 \rightarrow 3$
- B$3 \rightarrow 1 \rightarrow 2 \rightarrow 4$
- C$3 \rightarrow 2 \rightarrow 1 \rightarrow 4$
- D$3 \rightarrow 4 \rightarrow 2 \rightarrow 1$
