If f(a(i)) = 0 Then
①
Else
If i – f(a(i)) > max Then max = i – f(a(i))
End If
Next i
Text1.Text = Str(max)
则代码①处的语句可为（ ）

y = sin x， x∈R， y∈[–1，1]，周期为2π，函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x， x∈[–1，1]， y∈[–π/2，π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
