Carol sends Alice a hash. Alice includes that hash when she sends her LTC to Bob. The hash acts like a lock. You can only cash out the LTC if you provide (R) so the hash is tied to the LTC. Carol probably sends Alice the hash via wallet clients or even email (if Alice is technically proficient enough to know how to code) to tie it to the LTC.
