t = Val(Text1.Text)
If t <= a(n) Then
a(n + 1) = t
Else
L = 1: R = n
Do While L <= R
m= (L + R) \ 2
If _____①____ Then R = m - 1 Else L = m + 1
Loop
For j = n To L Step -1
_____②____
Next j
_____③____
End If
则横线①②③上的语句分别是（ ）
| A．①a(m) > t ②a(j) = a(j-1) ③a(R+1) = t |
| B．①a(m) < t ②a(j) = a(j-1) ③a(L) = t |
| C．①a(m) > t ②a(j+1) = a(j) ③a(R+1) = t |
| D．①a(m) < t ②a(j+1) = a(j) ③a(L) = t |

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
