Explanation:
Detailed explanation-1: -Internally 8085A works with a frequency of 3 MHz internally with clock frequency. Hence a crystal of frequency of 6-MHz crystal gets connected between X1 and X2. Every operation in the entire 8085 system occurs with the given synchronization process with the clock.
Detailed explanation-2: -In 8085, CALL instruction requires 18 T-states. i.e. for 17.5 x 0.33 x 10-6 = 5.8 s long.
Detailed explanation-3: -Concept: The base clock speed for the 8085A microprocessor is 3 MHz. It has a divide by two circuits which divides the externally connected clock by 2. The frequency of Crystal connected is 6 MHz.
