Final answer:

Without additional context or a motion graph, we cannot confirm if the velocity is zero, the acceleration is maximum, or the displacement is minimum at t=1.0s, nor can we assert that the speed is constant at that particular time.

Step-by-step explanation:

To determine which statement is true of the position at t=1.0s, we need to consider the descriptions of motion given. The most relevant information is that velocity is maximum at a certain time, and that if a displacement versus time plot is linear, then acceleration is either zero or a non-zero constant.

Additionally, a particle with an initial velocity and constant acceleration will have its maximum velocity when the acceleration is zero. Based on the given options and information, and knowing that maximum velocity does not imply zero velocity, we cannot confirm if the velocity is zero, the acceleration is maximum, or the displacement is minimum at t=1.0s without additional context or a specific motion graph.

Moreover, without any specific motion details indicating that the speed is constant, we cannot assert that the speed is constant at t=1.0s either.
