Couldnt understand the pinout of nucleo board, same pin is mentioned with 2 GPIO pins

I couldn't understand the pinout of the nucleo board

Here in CN8 the blue side pins is mentioned with both D43 and PC8. same in CN7 pin number 1 is mentioned with both PC6 and D16. But which of pin is actually connected to this specific header.

The A... and D... names are just for Arduino reference. The STM32 names whcih you also find in the data sheet, STM32CubeMX,... start with P for Port and a one letter + a decimal number in range 0..15 like PC8 etc..

Look at the schematics.

They are probably connected to both the CN8 and the CN7 pins.  <--  Sorry, I misread the question; it is as @KnarfB said.

Again, that would be clear from the schematics.

Also, the User Manual has tables showing which connector pins connect to what STM32 Port pins:

D43 on CN8 connects to PC8 on the STM32:

D16 on CN7 connects to PC6 on the STM32:

The Dxx pins are Arduino / Nucleo Morpho designators, not to be confused with PDx pins on GPIO Bank D

Other Pxy designations are for the IC. Check schematics and data sheet to assuage confusion and doubt..
