The ability to successfully conduct research is not solely dependent on one factor. Here's a breakdown of each option:

a. Possesses conversation skills: While conversation skills can be beneficial in conducting interviews or facilitating focus groups, they alone do not guarantee successful research. They are, however, a part of the broader skill set needed.

b. Possesses post-graduation degree: Having a post-graduation degree often means that the person has been exposed to research methodology. However, it doesn't necessarily mean they can successfully conduct research. It depends on the individual's understanding and application of what they've learned.

c. Someone who is a hard worker: Hard work is important in research due to the diligence and perseverance required. But without the necessary skills and knowledge, hard work alone may not lead to successful research.

d. Has studied research methodology: This is probably the most critical factor among the options. Understanding research methodology provides the necessary foundation for conducting research. However, it should be combined with hard work, the right skills (like conversation skills), and ideally, some level of education.

So, the most accurate answer would be a combination of all, with a strong emphasis on 'Has studied research methodology'.
