Fill in the blank in the following sentence by choosing the correct option out of the given ones.
He swam ________ the river to the other bank.

Correct option is A

Correct option: (a) across
Meaning of “across” (highlight):
• Across → from one side to the other side (crossing) (Hindi: आर-पार / एक किनारे से दूसरे किनारे तक)
Correct sentence: He swam across the river to the other bank.
Grammatical Rule (English):
• Use across for movement from one side to the other of a surface/area (river, road, field).
व्याकरणिक नियम (Hindi):
• जब गति एक तरफ से दूसरी तरफ हो, तब preposition across का प्रयोग होता है।
Why other options are incorrect:
• (b) into → अंदर की ओर जाना (river में), “other bank” तक crossing नहीं दिखाता।
• (c) in → स्थान बताता है, दिशा/crossing नहीं।
• (d) along → किनारे-किनारे/समानांतर चलना, पार करना नहीं।
Hence, option (a) is the correct answer.
