Which one of the following present-day states/regions was outside the boundaries of Ashoka's empire ?

The Brahmaputra valley in Assam lay outside the boundaries of Ashoka's Mauryan empire. Ashoka's edicts and archaeological evidence indicate that his empire extended into Baluchistan in the west (the Kandahar bilingual inscription confirms this), into northern Bengal (Mahasthangarh inscription in Bangladesh attests to Mauryan presence), and into the Kashmir valley (according to Buddhist traditions and Kalhana's Rajatarangini, where Ashoka is credited with founding Srinagar). However, the Brahmaputra valley region (Kamarupa/Assam) was never under Mauryan control.
