Answer:
Option B. Treasury Stock for $1,200
Step-by-step explanation:

Dr Cash Account $10,000
Cr Common Stock $2,000
Cr Paid In Capital $8,000
But when 100 shares were repurchased at $12 per share, then the accounting treatment would be
Dr Treasury Stock $1,200
Cr Cash Account $1,200
So the correct option is option B.
