Smaller devices such as PDAs have two options for wireless NICs some offer an optional SLED, which includes a type II PC card slot and additional battery.
Compact flash(CF) card option is wrong as compact flash card is very small in size and very thin as compared to the PC card it is very smaller and consumes less power as compared to PC card so additional battery is not required for compact flash card,infact PDA's are available with direct compact flash card interfaces inside them.
Secure digital card (SD)card is also wrong option because it is also smaller in size like the compact flash card so it also consumes less power therefore it don't requires an additional battery and this card also uses flash memory and more secure.
Mini PCI is also wrong option because Mini PCI is the smaller version of big sized PC cards and this card has same functionality as of PC cards but their size is very less than PC cards so they are smaller so consume less power so don't need additional battery.
