Choose the right form of verb: It is high time we (act) on the matter.

Explanation:

Correct Answer is: acted
It is high time যুক্ত বাক্যের পরে Subject থাকলে Verb past indefinite হয়। যেমন: It is high time we acted on the matter. উল্লেখ্য, It is high time এর পরে Subject না থাকলে infinitive (to+verb1) হবে। তখন It is high time to act on the matter হত।
