![## Task: Find the Minimal Elements of a Poset
Answer the following questions for the poset \( \{( \{1\}, \{2\}, \{4\}, \{1, 2\}, \{1, 4\}, \{2, 4\}, \{3, 4\}, \{1, 3, 4\}, \{2, 3, 4\}\}, \subseteq \) \).
### Question
Find the minimal elements. (Check all that apply.)
### Instructions
You must provide an answer before moving to the next part.

### Options
- [ ] \(\{1, 3, 4\}\)
- [ ] \(\{1\}\)
- [ ] \(\{2\}\)
- [ ] \(\{4\}\)
- [ ] \(\{2, 3, 4\}\)
### Notes
A minimal element in a poset is an element that is not greater than any other element. To determine the minimal elements, consider the subsets that do not properly contain any other subset within the given poset.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0405dc91-666b-4d31-b943-06bf4fafc05b%2F2775aa29-e007-46dd-9ec7-8e9c6b808054%2Fqz4ocbl_processed.png&w=3840&q=75)
