What is the order of magnitude of electric resistance of the human body (dry)?

Human dry-skin resistance varies widely, but typical values cited span from about 1×10^3 to 1×10^5 Ω in physics/educational sources and can extend to ~1×10^5–6×10^5 Ω in occupational-safety references. Given this spread, a representative single-order estimate for a dry human body is in the 10^4 Ω (tens of kiloohms) range, which best matches the provided options. Educational summaries list dry-skin resistance roughly 1,000–100,000 Ω [1], while safety guidance gives a typical dry range of 100,000–600,000 Ω [2]. Because values vary with contact area, moisture and path, 10^4 Ω is the closest practical order-of-magnitude choice among the options.
