Answer 1

The correct option is C Dylan

If carl is true, others must be false.

$\therefore$ It means Dylan also famous how to drive

But, it goes against the fact that only one

of them can drive $\therefore$ He is lying.

If Dylan is true Edmund must be lying

$\therefore$ It means carl also famous how to drive

But, it goes against the fact that only one

of them can drive $\therefore$ He is also lying.

If Edmund is true both carl and Dylan's

statement become false $\therefore$ Only one is saying

truth $\therefore$ Are assumptions are being kept in

mind $\therefore$ Edmund is true.

$\therefore$ Since Dylan was lying, it means

he famous how to drive.

$\therefore$ Dylan is the drive.
