Which of the following outputs will the below command sequence produce? echo '1 2 3 4 5 6' | while read a b c; do echo result: $c $b $a; done

The `read` command, when given multiple variable names, assigns the first word to `a` ('1'), the second word to `b` ('2'), and then assigns all remaining words on the line ('3 4 5 6') to the last variable `c`. The `echo` command then prints these variables in the order `$c $b $a`.

This output implies the variables were not assigned correctly or were echoed in their original order.

This output only shows the last three numbers, indicating an incorrect understanding of how `read` handles multiple words with multiple variables.

This output implies a complete reversal of all numbers, which would only happen if each number was read into a separate variable and then processed.

This output implies only the first three numbers were processed and reversed, but `read` assigns all remaining words to the last variable.
