Ans is 3 LXI rp, data
LXI is load register pair immediate which takes one register as input and 2 bytes immediate data. There are seven internal 8-bit registers: A(accumulator), B, C, D, E, H, L and SP, PC, flags.
This is generally used to load SP, memory pointer(commonly used H-L pair in 8085). Generally H-L, D-E, B-C register pairs are used. B, D, H hold the MSB and L, E, C hold the LSB.
e.g. LXI H, F800H ;this loads H-L pair with the value F800. F8 is stored in H, 00 is stored in L.
