Answer:
The wave is traveling in the +x direction.
Explanation:
The equation of a wave is given by the formula as :

Here,
A is the amplitude of wave
is the phase of wave
is the angular frequency of the wave
We need to find the correct statement out of given options. The given equation can be rewritten as :

Here, the propagation constant is negative. So, the wave is moving in +x direction. Hence, the correct option is (a).
