ADB = 180° - 100° = 80°

By remote interior angle theorem,
@ + ß = 80° ...(i)
2@ + ß = 100° (ii)

Subtracting (i)&(ii),
@ = 20° . So, ß = 60°

By comparing the above results we get that option (D) is not correct.

Checking,
sin(ß-@) = 1/√2
sin(60°-20°) = 1/√2
sin(40°) = 1/√2
but, sin40°≠1/√2

hence it's wrong.
i.e., the answer is option D.
