Economics question, Current Account

CFA Level I Economics
#1

An increase in the current account deficit cannot be generated by:
a. A decline in exportstraditional
b. Increase in external savings
c. Increase in private consumption
d. Decline in government revenue for taxes
e. An increase in current transfers

For me, all of them generate a deficit in CC.
According to the equation
CC = X-M = (S-I) - (G-T)

Is there something I am missing?

#2

why would decline in government revenue from taxes affect current account deficit?

#3

Because it makes T drops so CC goes down ? or I am wrong?

#4

I still did not master econ lessons, but what I know that decline in T will cause fiscal deficit not trade/current account deficit
