Conditions favourable for the formation of delta – include:
1. Unsheltered, preferably tidal coasts.
2. Passive vertical and lateral erosion in upper course of the river.
3. No strong current running right angles to river mouth.
4. No large lakes in the river course.

The correct option is C 3 and 4 only
(G.C. Leong . Chapter 5. Page – 44) 1 & 2nd are incorrect. Conditions favourable for the formation of the Deltas:
1. Active vertical and lateral erosion in the upper course of the river to provide extensive sediments to be eventually deposited as deltas.
2. The coast should be preferably tideless.
3. The sea adjoining the delta should be shallow or else the load will disappear in the deep waters.
4. There should be no large lakes in the river course to filter-off the sediments and there should be no strong current running at right angle to the river mouth, washing away the sediments.
