For a four noded quadrilateral elements, In uT=[u.v]T the displacement elements can be represented as u=N1q1+N2q3+ N3q5+ N4q7v= N1q2+N2q4+ N3q6+ N4q8

• A. n then the shape function can be represented as _____
• B. (N= left[ begin{array}{ |c c c c}q_1 & q_5 q_2 &q_6 q_3 &q_7 q_4 & q_8 end{array} right] )
• C. (N= begin{bmatrix}q_1 &q_3 &q_5 &q_7 q_2 &q_4&q_6&q_8 end{bmatrix} )
• D. (N= begin{bmatrix}q_1 q_2 end{bmatrix} )
• E. (N= begin{bmatrix}N_1 & 0 & N_3 & 0&N_5&0&N_7 & 0 0 & N_2 &0 &N_4&0&N_6&0&N_8 end{bmatrix} )
