The cache capacity of a computer storage system is 64B, each row is 8 bytes, a total of 8 lines, the line number is from 0 to 7, and the 2-way set associative mapping strategy is adopted. Initially, there is no data in the cache, and the valid bits of all lines are 0. Which lines of the cache can the data at the address 0x12 in the memory be loaded into?
