Step 1: Separate the offence from its penalty - the IPC first names the wrong, then assigns the punishment in a different section.
Step 2: Giving false evidence is defined in Section 191 and fabricating it in Section 192, but a definition alone carries no sentence.
Step 3: The actual sentence for perjury sits in Section 193, which authorises imprisonment up to seven years and a fine.
Step 4: Hence the section that punishes perjury is 193; the remaining options either only define the act or are unrelated.
\[\boxed{\text{Section 193}}\]
