The lines and will intersect if

Answer: (B)

Solution

Two lines and intersect when . Here $Missing argument for \bar\bar u×Missing argument for \bar\bar v = (Missing argument for \bar\bar b×Missing argument for \bar\bar c)×(Missing argument for \bar\bar a×Missing argument for \bar\bar b) = Missing argument for \bar\bar a [(Missing argument for \bar\bar b×Missing argument for \bar\bar c)·Missing argument for \bar\bar b] - Missing argument for \bar\bar b [(Missing argument for \bar\bar b×Missing argument for \bar\bar c)·Missing argument for \bar\bar a] = -[Missing argument for \bar\bar a\
