To identify the word with a different stress pattern, let's group the words based on their parts of speech and typical stress patterns:

1. **Nouns (generally stressed on the first syllable)**:
- **pocket** (POC-ket)
- **activity** (ac-TIV-ity)
- **pharmacy** (PHAR-ma-cy)
- **classmate** (CLASS-mate)
- **lesson** (LESS-on)
- **science** (SCI-ence)
- **facility** (fa-CIL-i-ty)
- **location** (lo-CA-tion)
- **teenage** (TEEN-age)
- **resident** (RES-i-dent)
- **province** (PROV-ince)
- **result** (re-SULT)

2. **Verbs (stressed on different syllables, often the second)**:
- **lower** (LOW-er)
- **attend** (at-TEND)
- **borrow** (BOR-row)
- **celebrate** (CEL-e-brate)
- **begin** (be-GIN)
- **interview** (IN-ter-view)
- **involve** (in-VOLVE)
- **enjoy** (en-JOY)
- **technology** (tech-NOL-o-gy)
- **different** (DIFF-er-ent)
- **office** (OF-fice)
- **fantastic** (fan-TAS-tic)

**Analysis of stress patterns**:
- Most of the words are either nouns or verbs with a regular stress pattern.
- Words like "celebrate," "interview," and "different" have secondary stresses.

**Conclusion**:
The odd one out might be **"activity"** or **"different"**, as "different" has a less common stress pattern for a noun (1st syllable stressed) compared to others in that column.

**Final choice**: **D. different**, as it does not follow the common stress pattern observed in the other words.
