You need to design a system to find the top 10 most frequent words in a very large text corpus. Which data structures and algorithms would you use to ensure efficiency in both space and time?

To efficiently find the top 10 most frequent words, you should use a Priority Queue (Heap) to keep track of the top frequencies and a Trie or Hash Map to count word occurrences. A Trie can be used to efficiently store and retrieve words, while a Priority Queue helps maintain the top frequencies. The other options are less efficient in terms of both time and space complexity.
