Which actress received the Best Actress award at the 64th National Film Awards announced in 2017 for her performance in a feature film?

Introduction / Context:
National Film Awards are among the most credible film honours in India because they are presented by the Government of India and decided by an independent jury. The 64th National Film Awards, announced in 2017 for films released in 2016, are important from an examination perspective. This question asks you to recall which actress received the Best Actress award at that edition.

Given Data / Assumptions:

• The award is the Best Actress award at the National Film Awards.
• The edition is the 64th National Film Awards.
• The announcement year is 2017.
• Options include four popular actresses from Indian cinema.

Concept / Approach:
To answer, you need to connect the 64th National Film Awards with the Malayalam film Minnaminungu and the relatively less mainstream actress who won for an intense character driven role. Many aspirants tend to assume that only nationally famous actresses from big budget films win such awards, but the National Film Awards often recognise subtle performances in regional cinema.

Step-by-Step Solution:
Step 1: Recall that the Best Actress award at the 64th National Film Awards went to Surabhi Lakshmi for her performance in the Malayalam film Minnaminungu. Step 2: In the options, Surabhi CM refers to the same actress Surabhi Lakshmi, who is sometimes written with initials in exam material. Step 3: Taapsee Pannu, Trisha Krishnan, and Anushka Shetty are well known actresses, but none of them were announced as the Best Actress winner at the 64th National Film Awards. Step 4: Therefore, Surabhi CM is the correct option.

Verification / Alternative check:
Lists of winners of the 64th National Film Awards clearly mention Surabhi Lakshmi as the Best Actress awardee for her role in Minnaminungu. These official and media sources confirm that the award did not go to Taapsee Pannu, Trisha Krishnan, or Anushka Shetty in that edition, even though they may have delivered notable performances in other films around that time.

Why Other Options Are Wrong:
Tapasee Pannu, more commonly spelled Taapsee Pannu, has received several honours and popular appreciation but did not win the Best Actress award at the 64th National Film Awards. Trisha Krishnan is a prominent actress in South Indian cinema, yet her name does not appear as the Best Actress winner in the 64th National Film Awards list. Anushka Shetty is also a leading actress best known for big budget films, but she did not receive the Best Actress National Award for that year.

Common Pitfalls:
Candidates often assume that a National Award must have gone to a nationally famous star from Hindi cinema or a widely publicised blockbuster film. This leads them to ignore comparatively lesser known names like Surabhi Lakshmi, who actually won. To avoid this error, it is important to study National Film Award lists carefully and note how frequently regional cinema performances are recognised at the highest level.

Final Answer:
The Best Actress award at the 64th National Film Awards announced in 2017 was given to Surabhi CM (Surabhi Lakshmi).
