Options

A. surface area of small pieces is smaller than the single log.
B. surface area of small pieces is larger than the single log
C. surface area of small pieces is equal to the single log
D. none of these

Since small pieces of wood have larger surface area than a single log of the same mass.
Therefore, the small pieces burn faster.
