The question asks for the year the Pharmacy Act was enacted in India. Instead of just recalling the year, let's place each option on the timeline of India's independence and post-independence legislative history to see which one fits.
Cross-checking against the broader timeline of Indian pharmaceutical legislation (the Drugs Act of 1940 preceding it, and the Pharmacy Act following shortly after independence to regulate the profession itself) confirms the year.
Therefore, the correct answer is 1948.
