Grating #2 must give a second order maximum.

Both gratings must also give second order maxima.

It is possible that neither grating gives a second order maximum.

Grating #1 must give a second order maximum.

Grating #1, which has less dispersion, will have a second order maximum where grating # 2 has its first order maximum.

Choose the last answer.
