Answer:

option d. at infinity

Explanation:

  • distance of object 'u' = 15 cm

  • radius of curvature of concave mirror = 30 cm

  • so, focus of concave mirror = 30/2 = 15 cm

  • object is placed at focus

  • so, image is formed at infinity

REASON

  • see the ray diagrams in image

  • so, the answer is option d. at infinity

hope this answer is helpful to you
