Final answer:
Without additional context, identifying the exact angle formed with the horizontal in section line drawings is not possible. However, 45° is a commonly used angle in technical drawings for section lines, which could suggest option B as a likely answer if following standard conventions.
Step-by-step explanation:
The question regarding the angle formed with horizontal upward to the left in section line drawing seems to be a technical detail related to drafting or engineering drawing techniques. While the question provides possible angles as options, it does not specify enough context to allow for a definitive answer. However, if the instructions hint at standard practices in engineering or technical drawing, the common angles used are 30°, 45°, and 60°. The 45° angle is often used for section lines which would make option B likely if adhering to that convention.
