Mnemonic-led approach: line up the false-evidence sections in order. IPC 191 = giving false evidence (the definition), IPC 192 = fabricating false evidence (the definition), IPC 193 = punishment for both (perjury). So the section that actually carries the penalty is 193, with imprisonment up to seven years plus fine. The trap option, IPC 197, is about issuing or signing a false certificate, which is a different offence. Since the question specifically asks for the punishment of perjury, options 191 and 192 are only definitions and must be ruled out, and 197 is unrelated. The remaining and correct answer is IPC 193.
