Which of the following is true about the ASCII table that we use to convert between numerical values and characters?

Group of answer choices

char types in C are usually one byte long, but the ASCII table has only $127$ entries. This means that some char values are out of ASCII range.

char types are less than one byte, meaning all char values have ASCII characters associated with them.

All $127$ ASCII table entries are present on standard keyboards, so every ASCII character can be typed from a keyboard.

char values can always be distinguished from other values because their bit representations can always be distinguished as characters$/$letters$.$
