(a) The first ionization enthalpy of K is less than that of Na and Li

(b) Xe does not have the lowest first ionization enthalpy in its group

(c) The first ionization enthalpy of element with atomic number 37 is lower than that of the element with atomic number 38.

(d) The first ionization enthalpy of Ga is higher than that of the d-block element with atomic number 30.
