Answer:

CGS Unit of Planck's Constant #h# is
#"erg"cdot s#

Explanation:

Planck's Constant #h# is a physical constant.

It has a value of #6.6261 xx 10^-27 cm^2 gm s^-1# in CGS units and #6.6261 × 10^-34 m^2 kg s^-1# in SI units.

As your question is in CGS system of units, we will use these only.

The famous equation #E=hxxnu#
Where #E# is the energy of a quantum of light.
#nu# is its frequency.
Lets us write units of all the known quantities
Unit of Energy is: erg
Unit of frequency is: Hz or #s^-1#
#E=hxxnu#
#"erg"="unit of "hxxs^-1#, solving for 'unit of #h#'

#"unit of "h="erg"/s^-1="erg"cdot s#
