In an electromagnetic spectrum, we can see a wide variety of possible electromagnetic radiations, which will differ in wavelength, energy, frequency and some other characteristics. The relationship of wavelength and energy is inversely proportional, which means, long wavelengths is equal to low frequency and energy. Energy of the radiation and frequency are directly proportional, which means that if we have a radiation with a high energy, we will also have a high frequency. Therefore, the answer will be the 1st option, Direct
