D as it is mentioned that the particle is travelling at a constant speed

Ans 2:

RAHUL S ROY from ST.XAVIERS HIGH SCHOOL,VAPI, VAPI,GUJARAT
Class : Class 7
option c is correct as acceleration means change of speed

Ans 3:

Hamsavarshini Swaminathan from St Anns Senior Secondary School, Roorkee

not c i think

Ans 4:

Venya Vikas from Chirec International , Hyderabad
Class : Class 7
Both option C and option D are correct as since it is moving in constant speed, it's acceleration will be zero and the direction will not change as it was not mentioned and the particle is travelling on a straight road

Ans 5:

RAHUL S ROY from ST.XAVIERS HIGH SCHOOL,VAPI, VAPI,GUJARAT
Class : Class 7
option c is correct

Ans 6:

Atharva Shrikhande from Euro School, Pune
Class : Class 9
both options "C" and "D" are correct in my opinion cause as the car is moving at a constant speed there is no acceleration and as the car is being ridden on a straight road direction of movement also does not change, Hence proving that both option "C" and "D" are correct. I hope my answer was helpful. A very Happy New Year to all
