Correct answer: Option B — 113°. Their absolute difference is 113.0°; the smaller angle is 113°. Option A (114°) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option C (112°) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option D (115°) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.

Hour-hand position = 30×1 + 0.5×22 = 41.0°. Minute-hand position = 6×22 = 132°. Their absolute difference is 91.0°; the smaller angle is 91°.

Correct answer: Option C — 41.5°. Hour-hand position = 30×1 + 0.5×13 = 36.5°. Minute-hand position = 6×13 = 78°. Their absolute difference is 41.5°; the smaller angle is 41.5°. Option A (46.5°) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option B (36.5°) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option C matches the verified calculation. Option D (51.5°) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.

Hour-hand position = 30×1 + 0.5×7 = 33.5°. Minute-hand position = 6×7 = 42°. Their absolute difference is 8.5°; the smaller angle is 8.5°.

Correct answer: Option A — 4. The Tuesday dates are 3, 10, 17, 24. Their count is therefore 4. Option A matches the verified calculation.
