Step 1: State the correct provision.
The President may promulgate an ordinance when either House is not in session under Article 123. Ordinances have the same effect as Acts but must be laid before Parliament and cease after six weeks of reassembly unless approved.
Step 2: Explain why each given option is wrong.
{Art. 125}—salaries/allowances of Supreme Court judges; {Art. 127}—ad hoc judges of the Supreme Court; {Art. 137}—review jurisdiction of the Supreme Court; {Art. 143}—President’s power to seek advisory opinions from the Supreme Court. None relates to ordinance-making.
Step 3: Conclude.
Because 123 is missing, the printed set is erroneous. In an exam, write {``Correct article: 123 ''} and briefly justify.
\[
\boxed{\text{Correct provision: Article 123 (Union) / Article 213 (State Governor).}}
