B Correct answer
Explanation

sed is the stream editor designed for text transformation and replacement. The command would be 'sed "s/hi india/HiIndia/g" filename'. awk can do replacements but is primarily for text processing and report generation. perl can do it but is a general-purpose language. emacs is an editor, not a command-line text processor.
