In Fig.99, `A B C D\ a n d\ E F` is a transversal intersecting AB and CD at P and Q respectively. The measure of `/_D P Q` is (a) `( b ) (c) (d) (e) 100^(( f )0( g ))( h ) (i)` (j) (b) `( k ) (l) (m) (n) 80^(( o )0( p ))( q ) (r)` (s) (c) `( d ) (e) (f) (g) 110^(( h )0( i ))( j ) (k)` (l) (d) `( m ) (n) (o) (p) 70^(( q )0( r ))( s ) (t)` (u)
