Or you can look up for 4046 link : https://www.ti.com/lit/ds/symlink/cd74hct4046a.pdf?ts=1666209598823

Give the reason and show how you get that answer.

p/s: believe if you choose 47 pf and 3.3k is not the right answer

The frequency range of the voltage controlled oscillator (VCO) in the 74HC4046A is determined by resistors R1 and R2 and capacitor C1. Assume resistor R2 is omitted, setting the minimum frequency to 0 Hz. The graphs in the datasheet show that a C1 of 10 pF and R1 of 15 k will select the desired center frequency of 10 MHz. Unfortunately, you don't have a 10 pF capacitor. What would be good alternative values for C1 and R1?
