A monochromatic light ray traveling in air enters a flat glass slab of thickness \(d\) at a non-zero angle of incidence \(\theta_1\) relative to the normal, refracts through the slab, and emerges back into air from the opposite parallel surface. Which of the following correctly identifies the direction of the emergent ray relative to the incident ray, and the effect on the lateral displacement of the emergent ray if the slab thickness is doubled to \(2d\) while keeping \(\theta_1\) constant?

Option	Direction of Emergent Ray	Lateral Displacement when \(d\) is Doubled
(A)	Angled toward the normal	Doubled
(B)	Angled away from the normal	Unchanged
(C)	Parallel to incident ray	Unchanged
(D)	Parallel to incident ray	Doubled
