Which statement is correct for a moving point?
A、If at is always equal to 0 and an is not equal to 0, then the point moves along a curve with varying speed.
B、If at is constant and an is not equal to 0, then the point moves along a curve with uniformly varying speed.
C、If at is not equal to 0 and an is always equal to 0, then the point moves along a curve with varying speed.
D、If at is not equal to 0 and an is always equal to 0, then the point moves along a straight line with constant speed.

以邻甲基环己烯甲醛为原料(A)，以异丙醇铝的苯溶液为催化剂，合成双烯201(B)，反应可写为2A→B，A的初始浓度为2.00mol·dm-1，在28℃进行反应，测得反应时间与A的转化率αA的关系如下表：
| t/h | 0 | 3 | 6 | 9 | 12 |
| αA | 0 | 0.46 | 0.63 | 0.72 | 0.77 |
试确定反应的速率方程式。
