Round Robin is the default startup method of loadbalancing. after the VS started up it changes to the set behaviour

I think the question is not correct or miss written. "A Citrix Administrator configured a load-balancing virtual server to utilize the least bandwidth load-balancing method. A service attached to this virtual server is brought into the effective state during production hours." The first statement talks about starting another SERVICE while the virtual load balancer is already up. In that case, it's slow start mode with Round Robin. "During the startup of a virtual server, which load-balancing method is used by default?" That statement talks about a virtual load balancer that is started from a down state, but has nothing to do with the first statement. How can I bring a service into an effective state when the whole virtual load balancer is about to start? Doesn't make sense to me, but I think the whole question is about the knowledge of slow start mode and for this A.

A seems correct. "The virtual server on a NetScaler appliance gets into a Slow Start mode or a Startup Round Robin mode whenever a new service is enabled or a new service is added to the farm." https://support.citrix.com/article/CTX108886/netscaler-load-balancing-slow-start-mode

Indeed it is. This article says LEASTCONNECTION is This is the default load balancing algorithm. https://docs.citrix.com/en-us/citrix-adc/current-release/load-balancing/load-balancing-customizing-algorithms.html

But its not the default LB CS startup algorithm. During startup of a virtual server, or whenever the state of a virtual server changes, the virtual server can initially use the round robin method to distribute the client requests among the physical servers. This type of distribution, referred to as startup round robin, helps prevent unnecessary load on a single server as the initial requests are served. After using the round robin method at the startup, the virtual server switches to the load balancing method specified on the virtual server.
