哪个是正确的赋值语句?

var (
  n = 3
  m int
  f float64
)

// one of the assignments below will be here

fmt.Println(n, m, f)

• n, m = 4, f
• n = false
• n, m, f = m + n, n + 5, 0.5 正确
• n, m = 3.82, "hi"

var (
  a int
  c bool
)

  var c, f string

• f = path.Split("assets/profile.png")
• _, f = path.Split("assets/profile.png") 正确
