In Indian beauty pageants, who among the following was crowned Pantaloons Femina Miss India World 2012, earning the right to represent India at the Miss World pageant?

Introduction / Context:
National beauty pageants such as Femina Miss India serve as platforms to select representatives for international contests like Miss World and Miss Universe. In 2012, the Pantaloons Femina Miss India World title was particularly notable because the winner went on to represent India on the global stage. Exam questions often ask for the name of the title holder for specific years, combining current affairs with popular culture. Remembering these winners helps build a rounded general knowledge base, especially for exams that include people and awards from diverse fields.

Given Data / Assumptions:

• The question concerns the Pantaloons Femina Miss India World title in 2012.
• The options include Vanya Mishra, Prachi Misra, Rochelle Maria, and Sandhya Agarwal.
• We assume that the question follows the widely publicised results of the 2012 pageant.
• Only one of the options corresponds to the winner of the Miss India World crown that year.

Concept / Approach:
In 2012, Vanya Mishra won the Pantaloons Femina Miss India World title. She represented India at the Miss World pageant and gained media coverage for her performance and various sub contest wins. The other names in the options either refer to other contestants or are generic sounding names included as distractors. The approach is to recall the exact name associated with the Miss India World 2012 title and match it with the options, while recognising that the similar sounding Prachi Misra and Rochelle Maria can easily confuse candidates who are not certain.

Step-by-Step Solution:
Step 1: Focus on the year 2012 and the specific title Pantaloons Femina Miss India World. Step 2: Recall that Vanya Mishra was crowned Miss India World 2012. Step 3: Check the options and confirm that her name appears among the choices. Step 4: Recognise that Prachi Misra and Rochelle Maria were not the holders of the Miss India World 2012 title. Step 5: Select Vanya Mishra as the correct answer.

Verification / Alternative check:
Verification can be done by checking reputable news archives, pageant websites, or official Femina Miss India records for 2012. These clearly list Vanya Mishra as the winner of the Miss India World title. Additional confirmation comes from coverage of her participation in Miss World 2012 and the various awards she received there. Such cross checks reinforce that Vanya Mishra is the accurate name to remember for this particular year and title combination.

Why Other Options Are Wrong:
Prachi Misra: Although similar in sound to Vanya Mishra, she did not hold the Miss India World 2012 crown, and the similarity is used mainly to confuse candidates.
Rochelle Maria: This name does not match the official winner of the 2012 Miss India World title in standard pageant records, so it is not correct.
Sandhya Agarwal: She is not associated with this particular beauty pageant title and appears only as a distractor.

Common Pitfalls:
A frequent mistake is to confuse Vanya Mishra with other contestants or later pageant participants due to the similarity in names or because candidates only vaguely remember a few names from pageant news. Another pitfall is to assume that the most familiar sounding name must be correct, without recalling the exact title year combination. To avoid such errors, it is helpful to link Vanya Mishra specifically to Miss India World 2012 and to the Miss World participation that followed, creating a clear memory association.

Final Answer:
The Pantaloons Femina Miss India World 2012 title was won by Vanya Mishra.
