1)t<0; i.e. t is negative; also as k lies to the left of t on the number line; therefore k is also negative, hence their product kt will be positive; which will lie to the right of t; hence 1 alone is sufficient to answer the question;

2)k<1; let k=0.1; t=0.9; kt= 0.09; which lies to the left of the number t;
now consider k=-2; t=-1; kt=2; which lies to the right of the number t; as here different results are possible depending upon the different values of k and t hence 2 alone is not sufficient to answer the question..!!

hence A
