Answer:
Option (3)
Explanation:
This question is incomplete; find the trigonometric functions in the attachment.
Since, sinθ is the reciprocal of cosecθ,
sinθ × cosecθ = 1
cosθ is the reciprocal of secθ,
cosθ × secθ = 1
And tanθ is the reciprocal of cotθ,
cotθ × tanθ = 1
Therefore, multiplication of these six trigonometric functions is 1.
Option (3) is the answer.
