Step 1: Identify the President's power to consult the Supreme Court.
The Supreme Court of India exercises original, appellate, and advisory jurisdictions; advisory jurisdiction allows the President to formally seek the SC's opinion on questions of law or fact of public importance.
Step 2: Identify the correct Article.
Article 143 of the Constitution confers Advisory Jurisdiction on the Supreme Court; when the President believes a question of law or fact of public importance has arisen, he may refer it to the SC - though the SC is not bound to respond.
Step 3: Distinguish from related Articles.
Article 141 = SC law is binding on all courts; Article 142 = SC's power to do complete justice; Article 144 = authorities must aid the SC; Article 143 = Presidential Reference for advisory opinion - making it the correct answer here.
