At the Asian Boxing Championships 2017 in Ho Chi Minh City, in which weight category did India boxer M C Mary Kom win the womens gold medal?

Introduction / Context:
M C Mary Kom is one of India most decorated boxers. In 2017 she added another major title by winning gold at the Asian Boxing Championships held in Ho Chi Minh City, Vietnam. This question asks you to recall the weight category in which she claimed that gold medal, a detail often included in sports current affairs.

Given Data / Assumptions:

• The event is the Asian Boxing Championships 2017.
• The venue was Ho Chi Minh City in Vietnam.
• M C Mary Kom won a womens gold medal there.
• Options list 48 kg, 51 kg, 54 kg and 57 kg as possible weight categories.

Concept / Approach:
Mary Kom has competed in different weight divisions during her career, but she is especially associated with the lightest categories at continental events. In the 2017 Asian Championships, she competed in and won the 48 kg category. The approach is to remember that this tournament marked her return to continental gold in the light flyweight band.

Step-by-Step Solution:
Step 1: Recall Mary Kom performance at the Asian Boxing Championships 2017.Step 2: Note that she was aiming to succeed in a light weight division after moving from Olympic 51 kg to her more natural lower category.Step 3: The final in which she won gold was contested in the 48 kg category, also known as light flyweight.Step 4: Compare this with the options. 51 kg and 54 kg are higher categories, and 57 kg is even heavier, none of which match the specific title she won in 2017.Step 5: Therefore, the correct answer is 48 kg.

Verification / Alternative check:
Sports news reports from late 2017 highlighted that five time world champion Mary Kom captured her fifth Asian Championship gold in the 48 kg division at Ho Chi Minh City. They specifically mentioned that she won in her preferred light flyweight category. No report describes her 2017 Asian Championships gold as being in 51 kg, 54 kg or 57 kg, which confirms the correct weight class.

Why Other Options Are Wrong:
Option B, 51 kg, is associated with her Olympic campaigns but not with this specific gold at the 2017 Asian Championships. Option C, 54 kg, and option D, 57 kg, are higher weight classes where Mary Kom has not traditionally targeted major titles. These categories do not match the event details in the question.

Common Pitfalls:
Candidates may confuse the different weight categories in which Mary Kom has competed over the years or may default to 51 kg because of Olympic coverage. Another pitfall is not reading the year carefully and mixing this gold with achievements in other tournaments. To avoid such issues, remember that the 2017 Asian Championships victory at Ho Chi Minh City came in the 48 kg category.

Final Answer:
At the Asian Boxing Championships 2017, Mary Kom won gold in the 48 kg weight category.
