Answer
e. acidosis
Work Step by Step
Increased excretion of ammonium chloride in the urine most likely indicates acidosis.
The body uses ammonia as a base to neutralize acid. The ammonia gains a hydrogen ion creating ammonium ions, which then bind to chloride ions. The resulting ammonium chloride is excreted in the urine. The excretion of ammonium chloride ions indicates that there are extra $H^+$ ions in the body and thus the body is in a state of acidosis.
