Step-by-step explanation:

asinA=bsinB    ...(1)

As we know from the sine rule,

i.e asinA=bsinB=csinC=k  (say)

sinA=ka,   sinB=kb

Put the above values in eq (1)

aka=bkb

a2=b2

a=±b

as side can't be negative 

a=b

A triangle having two sides equal is Isosceles.

Hence, option (A) is correct.
