Given: HI_L_H_K_MH_ _LMHIK_ _

Let's check options:

Option (a): MKILIKLM

Sequence:  H I M L K  /  H I K L M  /  H I K L M  /  H  IK L M (Not a Logical Sequence)​
​Option (b): MKLIIKML

Sequence:  H I M L K  /  H L K I M  /  H I K L M  /  H  IK M L  (Not a Logical Sequence)​
​Option (c): KMLIIKML

Sequence:  H I K L M  /  H L K I M  /  H I K L M  /  H  IK M L  (Not a Logical Sequence)​
​Option (d): KMILIKLM

Sequence: H I K L M  /  H I K L M  /  H I K L M  /  H  IK L  M   (Logical sequence follow)

Thus, the correct option is (d) KMILIKLM
