Bash Scripting - Conditionals

What will be the output of this script if myfile.txt exists and is readable but not writable?

if [ -r myfile.txt ]; then echo "Readable"; else echo "Not readable"; fi
if [ -w myfile.txt ]; then echo "Writable"; else echo "Not writable"; fi

AReadable\nWritable

BNot readable\nWritable

CReadable\nNot writable

DNot readable\nNot writable

Step-by-Step Solution

Solution:

Step 1: Check readability condition
The file exists and is readable, so [ -r myfile.txt ] is true, printing "Readable".
Step 2: Check writability condition
The file is not writable, so [ -w myfile.txt ] is false, printing "Not writable".
Final Answer:
Readable\nNot writable -> Option C
Quick Check:
Readable true, writable false = A [OK]

Quick Trick: Check each permission separately with -r and -w [OK]
