Correct option is (c) Blaney-Criddle Formula

The best I can explain: Blaney-Criddle Formula is expressed as Cu = k.f

Where, f = p/40 [1.8t + 32], Cu = seasonal consumptive use and k = crop factor. Crop factor is determined by experiments under environmental conditions of the particular area for each crop.
