one question. why A is wrong.

If i substitute 0.4 in equation i get 1 as answer.

Any value from 0.4+ when placed in equation will give a value greater than 1 . It might be slightly higher than 1 but will be higher, so why would it be wrong.?

Option (D) gives the complete range of x but yes, (A) satisfies the inequality and gives the partial range. The question needs to be worded better.
