The correct option is B Mauryas
The coins of Mauryan period manifest that they were cut and clipped for
proper weight and adjustments. The coins were struck in conceivable
geometric form including round, oval and elliptical. The coins showcased only one symbol and it had been observed that the idea was perhaps
taken from the Vedic period. Later the number of symbols increased and
the punching devices of these coins had no inscriptions but they bore a
number of symbols. The symbols varied from geometrical and floral
patterns, with hills, birds, animals, reptiles, human figures and the
like. A particular symbol stands for the representation of a particular
place or area. Often the flans or planchets of the coins were smaller
than the size of the punches. Sometimes, in an attempt to accommodate
the complete symbols; they were punched together, one overlapping
another. Several symbols were introduced in the ancient Indian coins
abut with the commencement period of the Mauryan empire the symbols got a
bolder look. The earlier coins with five symbols were a representation
of a particular feature. Even silver punch marked coins were also issued
during this age. Silver coins were found in four denominations viz.
'pana', 'ardha-pana', 'pada' and 'asta-bhaga' or 'ardhapadika'. These
coins were issued from the mints of the Mauryan Empire as per
'Arthasastra'.
