a. food supply
b. storage, distribution and handling
c. pastoral industry and fishing
d. besides increasing
e. by preventing wastage in
f. the productivity from agriculture
g. can be increased

The correct sentence would be: Besides increasing the productivity from agriculture, pastol industry and fishing. Food supply can be increased by preventing wastage in storage, distribution and handling. The answer is option C.

Option A: In this one ,D-C-F would form "besides increasing pastoral industry and fishing the productivity from agriculture" doesn't make coherent sense.

Option B: This would form "Besides increasing food supply the productivity from agriculture can be increased by preventing wastage in pastoral industry and fishing, storage, distribution and handling" . This statement lacks the logical flow where the sentence talks about other than productivity from agriculture, the food supply could be increased by reducing wastage.

Option D:In this sequence, F-C-E would give "the productivity from agriculture pastoral industry and fishing by preventing wastage in" does not form a coherent sentence, so this option is eliminated.
