2) pH normal ; HCO3 high; pCO2 low
3) pH low; HCO3 low; pCO2 high

1 and 3 are the same options. maybe one of them had low pCO2 as an option.
answer actually should be - pH low;HCO3 low and pCO2 low and also potassium is reduced.

stage 1 ventilatory stimulation decreased pCO2,increased pH(resp alkalosis).
stage 2 increased renal bicabonate excretion(compensated resp alkalosis)
stage 3 respiratory acidosis medullary ventilation depression decreased pH.
metabolic acidosis acidic salicylate accumulates increased lactic acid prod & released into blood decreased pH by 2nd process.
stage 4 profound metabolic & resp acidosis.
