need help for Stat question

If sample data is such that for a one-tailed test of μ you can reject H0 at the 1% level of significance, can you always reject H0 for a two-tailed test at the same level of significance? Explain your answer.

a. No. The P-value for the two-tailed test could be greater than 0.01.

b.Yes. The P-value for the two-tailed test could be greater than 0.01.   

c. No. If H0 for a one-tailed test is rejected at the 1% level of significance, it will never be rejected for a two-tailed test at the same level of significance.

d.Yes. If H0 for a one-tailed test is rejected at the 1% level of significance, it will always be rejected for a two-tailed test at the same level of significance.
