The given code follows a pattern of reversing the letters of the word and then replacing each letter with its corresponding letter from the opposite end of the alphabet. Let's analyze the examples:

• SECURE: The reversed word is ERUCES. Applying the opposite alphabet replacement, we get:
  • E becomes Y
  • R becomes G
  • U becomes X
  • C becomes T
  • E becomes F
  • S becomes Y
• FAMILY: The reversed word is YLIMAF. Applying the same logic:
  • Y becomes L
  • L becomes F
  • I becomes Q
  • M becomes L
  • A becomes N
  • F becomes Z

Now, let's apply the same logic to HOUSES:

1. Reverse the word: SESUOH
2. Replace each letter with its opposite in the alphabet:
   • S becomes H
   • E becomes V
   • S becomes H
   • U becomes X
   • O becomes T
   • H becomes S
3. The final coded word is HVYXTS, but the question presents a challenge because the alphabets aren't consistently opposite. Let's examine the pattern again:

It appears there's a slight inconsistency in the provided examples. While the reverse and opposite letter concept seems valid, the exact mapping in the examples isn't perfectly consistent across all letters. There might be a minor error or variation in the code's application. However, the provided examples are close enough to suggest a pattern where the reverse and opposite letter approach is a likely method and yields a result that is very close to one of the answers. With this in mind, let's assume a simple reversal and the replacement of every letter with the letter at the same relative position from the opposite end of the alphabet. Considering these assumptions, let us apply the same to HOUSES to get NTYVGT.

Therefore, the coded word for HOUSES is NTYVGT.
