Which of the following personalities has been appointed as a UNICEF Goodwill Ambassador?

Introduction / Context:
The United Nations Children's Fund (UNICEF) often appoints well known public figures as Goodwill Ambassadors to promote children's rights and draw attention to global issues such as education, health and equality. These ambassadors can be actors, athletes, musicians, or digital creators. General knowledge exams frequently ask about which celebrity was appointed to such roles. This question focuses on a particular appointment involving a globally popular YouTuber and entertainer of Indian origin.

Given Data / Assumptions:

• The designation mentioned is "UNICEF Goodwill Ambassador".
• The options list names including Lilly Singh, Iravati Dubey, Lillete Dubey, Rosa Mendes and Nargis Fakhri.
• Only one of these individuals is widely known to have been officially appointed as a UNICEF Goodwill Ambassador.
• We assume standard information reported by UNICEF and international media.

Concept / Approach:
Lilly Singh is a Canadian YouTuber, comedian and actress of Indian origin, famous online as "Superwoman". She was appointed a UNICEF Goodwill Ambassador, focusing on child rights and gender equality. The other names in the options either refer to Indian actors not known for this UNICEF role, or to unrelated international personalities. Therefore, the correct approach is to identify which name has appeared in official UNICEF announcements as a Goodwill Ambassador.

Step-by-Step Solution:
Step 1: Recall that UNICEF often collaborates with celebrities to raise awareness about children's issues.Step 2: Recognise Lilly Singh as a social media star and comedian who has been involved in several global campaigns related to empowerment and equality.Step 3: Remember news reports highlighting that she was appointed as a UNICEF Goodwill Ambassador.Step 4: Compare with the other options: Iravati Dubey is not widely recognised as a UNICEF ambassador; Lillete Dubey is an Indian theatre and film actress; Rosa Mendes is a professional wrestler; Nargis Fakhri is a film actress and model.Step 5: Conclude that Lilly Singh is the correct answer.

Verification / Alternative check:
A helpful verification is to think of the type of campaigns and platforms each person uses. Lilly Singh has worked with the United Nations on campaigns for gender equality and girl's education, appearing in official UN and UNICEF videos. The other listed names are known mainly for their performances in film, theatre or sports entertainment and are not commonly introduced as UNICEF Goodwill Ambassadors in news coverage. This confirms that Lilly Singh is the accurate choice.

Why Other Options Are Wrong:
Iravati Dubey and Lillete Dubey are associated with acting and theatre; there is no major, widely reported UNICEF Goodwill Ambassador appointment for them. Rosa Mendes has a background in professional wrestling and sports entertainment, not in UN ambassadorship. Nargis Fakhri is an actress and model, again without the specific UNICEF title discussed in GK books. These names function as plausible sounding distractors but do not match the actual UN appointment.

Common Pitfalls:
Exam takers might choose Lillete Dubey or Nargis Fakhri simply because they recognise those names from films, assuming that any popular actress might be picked by UNICEF. Another pitfall is to overlook the growing importance of digital creators like Lilly Singh in international campaigns and underestimate their likelihood of being chosen as ambassadors. To avoid these errors, aspirants should update their current affairs knowledge regularly and remember that UNICEF partners with a wide range of celebrities, including YouTubers and influencers, not just traditional actors.

Final Answer:
The correct answer is Lilly Singh.
