Answer:

(a) Here, two lines contain point E, one of them is \[\overset{\leftrightarrow }{\mathop{AE}}\,.\] (b) Here, one line is passing through A, i.e.\[\overset{\leftrightarrow }{\mathop{AE}}\,.\] (c) Line on which O lies, is \[\overset{\leftrightarrow }{\mathop{CO}}\,\]or \[\overset{\leftrightarrow }{\mathop{CO}}\,.\] (d) There are two pairs of intersecting lines, i.e. are \[\overset{\leftrightarrow }{\mathop{CO}}\,,\overset{\leftrightarrow }{\mathop{AE}}\,\] and \[\overset{\leftrightarrow }{\mathop{AE}}\,,\]\[\overset{\leftrightarrow }{\mathop{EF}}\,.\]
