With these TLVs, IS-IS metrics can have values up to 16,777,215 (224 – 1). By default, Junos OS supports the sending and receiving of wide metrics. https://www.juniper.net/documentation/us/en/software/junos/is-is/topics/concept/isis-wide-metrics.html

C+D. Wide and Narrow advertised by default. Export policy not required to export from L1 to L2 when only wide metrics enabled.

I think the question might be wrong. narrow metrics use 6 bits, and wide metrics use 24 bit. Both narrow and wide are enabled by default, but narrow is prefered. So i would say answer C is correct, but ABD is not correct, unless the answer is abit wrong?

Not A "Don't confuse wide-metrics with wide-metrics-only, as I stated before wide-metrics are enabled on Juniper by default," https://networkengineering.stackexchange.com/questions/64469/understanding-the-is-is-wide-metric-style-for-traffic-engineering-in-juniper-mx

Also explained here by juniper where the command is explained to change how the already enabled by default "wide metric" changes the parameters of this metric's algorithm https://www.juniper.net/documentation/us/en/software/junos/is-is/topics/concept/isis-wide-metrics.html
