The three dimensional structure of $\mathrm{CH}_4$ is given below. The bonds are labelled as W, X, Y and $\mathrm{Z}$. What are the bonds lying in the plane (A), projecting out of the plane away from the observer (B) and projecting out of the plane towards the observer (C)?

• Correct answer
  A

  \begin{array}{lll} A & B & C \\ X,Y & Z & W \end{array}
• B

  \begin{array}{lll} A & B & C \\ Z & W & X,Y \end{array}
• C

  \begin{array}{lll} A & B & C \\ X,Y & W & Z \end{array}
• D

  \begin{array}{lll} A & B & C \\ W & X,Y & Z \end{array}

Hence, the correct answer is option: 'A'.
