#### Statement I : Graph of y = tan x is symmetrical about origin

Statement II : Graph of is symmetrical about y-axis

Maths-General

- If both (A) and (R) are true, and (R) is the correct explanation of (A) .
- If (A) is true but (R) is false.
- If (A) is false but (R) is true.
- If both (A) and (R) are true but (R) is not the correct explanation of (A) .

#### Answer:The correct answer is: If both (A) and (R) are true, and (R) is the correct explanation of (A) .y = tan x is odd function so must be symmetrical about origin & is decretive of y = tan x so it must be even imply symmetrical about y-axis or vice-versa
