Select the number from among the given options that can replace the question mark (?) in the following series.
$$1,3,9,27,?$$

The given number series follows a geometric pattern where each subsequent number is multiplied by $3$:$1\times 3=3$$3\times 3=9$$9\times 3=27$ Following the same logic, the next term will be:$27\times 3=81$
