Explanations:The question requires an understanding of the correct tense to use when describing current weather conditions. The sentence "It _____ rainy and sunny in Kolkata today" is referring to the current weather in Kolkata, which necessitates the use of the present tense. The present tense "is" is used to describe ongoing or current conditions, while the past tense "was" is used to describe conditions that have already occurred.
In this context, the correct answer is "is" because the sentence is describing the current weather conditions in Kolkata. The use of "is" indicates that the weather is currently both rainy and sunny, which is a common occurrence in many places, including Kolkata, where weather can be unpredictable and change rapidly.
It is important to note that the use of "was" would be incorrect in this context because it would imply that the weather conditions were in the past, which is not the case. The sentence is describing the current state of the weather, not a past state.
Additionally, the options "either (A) or (B)" and "neither (A) nor (B)" are incorrect because they do not provide a clear and accurate description of the current weather conditions. The sentence requires a present tense verb to accurately describe the current state of the weather, and "is" is the correct choice for this purpose.
Understanding the correct use of tenses in describing current conditions is crucial for clear and accurate communication. The present tense "is" is the appropriate choice for describing ongoing or current conditions, while the past tense "was" is used for conditions that have already occurred. In this case, the correct answer is "is" because the sentence is describing the current weather conditions in Kolkata.
