Option 1 -> The supply curve intersects the X-axis, making it inelastic.
Option 2 -> Unit elasticity occurs when the supply curve passes through the origin.
Option 3 -> Elastic supply occurs when the curve intersects the Y-axis.
Option 4 -> Zero elasticity means a vertical supply curve.
Hence, Option 1: Elasticity of supply is less than one -> When a straight-line supply curve shoots from/intersects the X-axis (quantity axis), it means the curve starts at a positive quantity on the horizontal axis. For any linear supply curve, the position of intercept determines elasticity: (a) Intercepts X-axis → Es < 1 (inelastic), (b) Passes through origin → Es = 1 (unit elastic), (c) Intercepts Y-axis → Es > 1 (elastic). Since this curve shoots from the X-axis, the percentage change in quantity supplied is less than the percentage change in price, making it inelastic. -> correct
