The abbreviation that means 'history' is:

The idea here is recognizing common medical abbreviations. hx is the shorthand for history, so in a radiography context it refers to the patient’s history, including prior illnesses, procedures, allergies, and previous imaging. That makes it the correct choice for meaning “history.” The other options don’t fit this meaning: bx stands for biopsy, a procedure to take tissue for examination; hs isn’t a standard abbreviation for history and can have other meanings in different contexts; MI most commonly means myocardial infarction (a heart attack).
