Question

By default, the GPIO pins in Raspberry Pi are configured as
1.Input except pins 14 and 15
2.Output except pins 14 and 15
3. Bcm
4. GPIO

Answer 1

The answer is Option 1.

By default, the General Purpose Input Output (GPIO) pins in the Raspberry Pi are configured as Input except pins 14 and 15. There are totally 17 basic GPIO pins, of which all the pins except 14 and 15 are by default configured as inputs. To make use of these pins, they must be configured as either inputs or outputs depending on the platform they are to be used.
