The correct option is Cousin.

Let us analyze the given family relations step-by-step to determine the relationship between Fred and David:
1. Harry is married to Grace.
2. Alan is the only son of Grace, and Becky is Alan's sister. This means Alan and Becky are siblings, both being the children of Harry and Grace.
3. Emma is the wife of Alan.
4. Fred is Emma's son. Since Emma is married to Alan, Fred is the son of Alan and Emma.
5. Chris is the husband of Becky.
6. David is Chris's son. Since Chris is married to Becky, David is the son of Becky and Chris.

Now, comparing Fred and David:
- Fred is the child of Alan.
- David is the child of Becky.
- Alan and Becky are brother and sister (siblings).

Since their parents (Alan and Becky) are siblings, Fred and David are first cousins to each other. Therefore, Fred is the Cousin of David.
