0An infinitely long wire is kept along \( z \)-axis from \( z=\infty \) to \( z=+\infty \), having uniform linear charge density \( \frac{10}{9} \mathrm{nC} / \mathrm{m} \). The electric fleld at point \( (6 \mathrm{~cm}, 8 \mathrm{~cm}, 10 \mathrm{~cm}) \) will be
(A) \( (120 \hat{i}+160 \hat{j}+200 \hat{k}) \mathrm{V} / \mathrm{m} \)
(B) \( 200 \vec{k} V / \mathrm{m} \)
(C) \( (160 \hat{i}+120 \hat{j}) \vee / \mathrm{m} \)
(D) \( (120 \hat{i}+160 \hat{j}) V / \mathrm{m} \)
