Rebalancing an Hedge with derivatives product

CFA Level III
#1

To rebalance the SEK/GBP hedge, and assuming all instruments are based on SEK/GBP, Björk would buy:

  1. GBP 7,000,000 spot.
  2. GBP 7,000,000 forward to December 1.
  3. SEK 74,812,500 forward to December 1.

Why is it B and not A. I mean they are rebalancing the hedge now
