A: Neurogenic bladder, B: Acute prostatitis, C: Prostate cancer, D: Urethral stricture, E: Benign prostatic hyperplasia,  <response>: Based on the patients age, symptoms of frequent urination, weak urinary stream, and enlarged prostate on exam, the most likely diagnosis is benign prostatic hyperplasia BPH. BPH is a common condition in older men that leads to urinary symptoms due to enlargement of the prostate. The other options can be ruled out based on the lack of supporting history, exam findings, or risk factors. Neurogenic bladder would present with urinary retention rather than frequent urination. Acute prostatitis would cause pain with urination. Prostate cancer is possible but less likely than BPH in the absence of concerning prostate exam findings. Urethral stricture could cause weak stream but would not explain the frequent urination. E: Benign prostatic hyperplasia
