Best answer
Right choice is (a) Yes

For explanation I would say: The Atmega32U4, like most other chips has an index corner which is used to identify the numbering of the pins when reading the pin configuration of the chip. Almost all chips have a similar index corner without which, numbering of the pins would be very difficult.
