Stream redirection operators in Bash are used to redirect the standard input, standard output, and standard error streams to or from files or other commands. Here are the explanations of the given options:

A. <: This operator is used to redirect the standard input stream from a file. For example, the command sort < file.txt will sort the contents of file.txt and print the result to the standard output.

B. <<<: This is not a valid stream redirection operator in Bash. It is likely a typo and should be ignored.

C. >: This operator is used to redirect the standard output stream to a file. For example, the command echo "Hello World" > file.txt will write "Hello World" to file.txt.

D. >>>: This is not a valid stream redirection operator in Bash. It is likely a typo and should be ignored.

E. %>: This is not a valid stream redirection operator in Bash. It is likely a typo and should be ignored.
