What distinguishes an SPLD $($Simple Programmable Logic Device$)$ from a CPLD $($Complex Programmable Logic Device$)?$

A$)$ SPLDs are more complex and have more logic blocks than CPLDs

B$)$ CPLDs are typically faster and have more logic gates than SPLDs

C$)$ SPLDs are used for digital$-$to$-$analog conversions

D$)$ CPLDs are limited to $4-$input logic gates, while SPLDs can use any number of inputs
