d.Methyl alcohol intoxication
Anser & Explanation:
[HIDE] The answer is d, Methyl alcohol intoxication.

Isoniazid, ethambutol, streptomycin, and other drugs may produce similar field cuts, but the blind spots developing with these toxins usually appear subacutely or chronically rather than abruptly.
