Select the Adverb of place.

Adverbs are classified by what question they answer. An adverb of place answers ‘where?’ and normally modifies a verb by giving a location, direction, or position (for example: here, there, everywhere, abroad) — it functions independently, without needing a preposition.

In this sentence, ‘Here’ directly indicates a location and answers where — it functions as an adverb of place on its own. ‘Almost’ instead answers ‘to what extent’, so it is an adverb of degree, not of place. ‘Agra’ and ‘Japan’ are proper nouns naming specific places; grammatically they function as nouns and need a preposition such as ‘in’ or ‘to’ to play any adverbial role — they are not adverbs by themselves.

• Almost — an adverb of degree (as in ‘almost finished’), not of place.

• Agra — a proper noun (a city name); needs ‘in Agra’ to function adverbially.

• Japan — a proper noun (a country name); needs ‘to Japan’ or ‘in Japan’ to function adverbially.

Therefore, ‘Here’ is the word that functions as an adverb of place.
