Volume based is not able for ECMP A and D correct

Took me some digging to find the source: https://docs.fortinet.com/document/fortigate/7.4.6/administration-guide/25967/equal-cost-multi-path

A. If SD-WAN is enabled, you control the load balancing algorithm with the parameter load-balance-mode. D. If SD-WAN is disabled, you configure the load balancing algorithm in config system settings.

A and D are correct

Correct is AD

Config system settings if SDWAN is disabled. Use load balance mode if SDWAN is enabled.

SD-WAN is enabled: v4-ecmp-mode is hide and you control the ECMP algorithm with the load-balance-mode setting. SD-WAN is desabled ECMP algorithm is set on the CLI: config system settings.

Yip A and D it is.

It should be A and D

AD, "When SD-WAN is enabled, FortiOS hides the v4-ecmp-mode setting and replaces it with the loadbalance-mode setting under config system sdwan. That is, when you enable SD-WAN, you control the ECMP algorithm with the load-balance-mode setting." The statement C. If SD-WAN is enabled, you can configure routes with unequal distance and priority values to be part of ECMP is incorrect because ECMP requires routes to have equal cost, which means that the routes must have the same distance and priority values to be considered for load balancing. In contrast, ECMP specifically balances traffic across multiple paths that have equal cost, hence the term "equal-cost" in ECMP. If the distance or priority values are different, those routes would not be eligible for ECMP. Therefore, A and D are correct, and C is incorrect.

A and C are correct. B is incorrect. While when SDWAN is disabled, you have the v4-ecmp-mode available. However, "volume-based" is a load-balance-mode setting and is not available. D is incorrect because if you disable SDWAN, you turn off the load balancing algorithm.
