Step 1: Understanding the Concept:
Chickpea agronomy differs sharply from cereal agronomy on the point of water. It is grown as a low-water, rainfed leaning crop, and both too little and too much water hurt it. We check each of the five statements against this working picture.
Step 2: Key Formula or Approach:
There is no single formula here, we weigh each claim against known crop-water behavior in chickpea: its critical growth stages, its total water budget, its salt tolerance, its irrigation method, and its lodging risk.
Step 3: Detailed Explanation:
Statement (A) holds up, because flowering and pod filling are the two stages where chickpea yield is most sensitive to a moisture gap, any shortfall here directly cuts flower or seed number.
Statement (B) also holds up, the crop's full water requirement across the season, counting stored soil moisture, rain, and any irrigation, is generally quoted in the 400 to 600 mm band.
Statement (C) does not hold up, chickpea's salt tolerance threshold is quite low, close to 1.8 to 2 dS/m, so at 10 mmhos/cm salinity the yield hit is much worse than 55%, the number given is too mild for that salinity level.
Statement (D) does not hold up either, since chickpea cannot take standing water around its base, growers use the furrow method rather than flooding the whole check basin.
Statement (E) holds up, because in the cool, low evaporative demand winters of North India, adding irrigation pushes the plant into excess leafy growth, and that soft, tall growth is what makes it lodge.
So only (A), (B) and (E) stand as true.
Step 4: Final Answer:
The correct combination is (A), (B) and (E) only, which is option 1.
\[ \boxed{\text{Option 1}} \]
