{'wheat': [4, 1, 2, 2], 'good cultivation': [0, 1, 0, 0], 'conditions': [0, 0, 0, 1], 'moderate rainfall': [1, 1, 0, 0], 'moderate temperature': [1, 1, 0, 1], 'low rainfall': [1, 1, 1, 0], 'low temperature': [1, 1, 1, 5], 'high temperature': [0, 2, 3, 11], 'heavy rainfall': [1, 1, 4, 3]}

Wheat thrives best under moderate conditions. Let`s explore all the options:

Option 1: Moderate temperature and moderate rainfall: Wheat requires a moderate climate with temperatures between 10-24 Celsius and a rainfall of 30-100 cm annually. Thus, this option provides the most suitable environment for wheat to prosper.

Option 2: High temperature and heavy rainfall: High temperatures can stress the wheat plant leading to reduced yields, and heavy rainfall can cause soil erosion and waterlogging, both detrimental for wheat growth.

Option 3: High temperature and moderate rainfall: While moderate rainfall is beneficial for wheat, high temperatures can inhibit wheat growth and cause reduced productivity.

Option 4: Low temperature and low rainfall: Wheat can`t grow at low temperatures and drought conditions as it needs ample water during key growth stages. Low rainfall can lead to water deficiency and low temperature can slow down or halt wheat’s growth and grain formation.

Therefore, option 1 provides the most appropriate environmental conditions, with both moderate temperature and moderate rainfall for good cultivation of wheat.
