Select the most appropriate option to fill in the blank.
If the weather forecast proves accurate, we ______ heavy snowfall in the region tomorrow.

Correct option is A

The correct option to fill in the blank is (a) should have.
Explanation: The sentence talks about a possible future event based on a condition (“if the weather forecast proves accurate”), so we need a modal of probability in future context. “Should have” expresses likelihood or probability.
Example: If the roads are closed, we should have an alternate route planned.
Why other options are incorrect:
· (b) need to have – Implies necessity, not probability. (आवश्यकता)
· (c) are having – Present continuous tense; not appropriate for a future event with uncertainty. (वर्तमान समय का प्रयोग)
· (d) must have – Expresses certainty, but the sentence indicates possibility, not certainty. (अनिवार्यता दर्शाता है)
